Title: Software - Jazz's weakest part
Post by: stani on May 25, 2025, 04:30:52 PM
1 ) every time the car is turned on, a "Warning" appears on the main display, it's annoying and there's no way to turn it off.

2 ) System volume - System sounds - you can't set the value to "0", the lowest value is "3"

3 ) I also mind the volume of the turn signals, but there's only the option "high", "medium" and "low", no scale from 0 to 10. Almost no difference between "high", "medium" and "low". I have it on low and it's still quite loud.

4 ) the worst of all sounds is the "speed alarm" - it's extremely annoying and noisy. There's no way to turn it permanently off, you can't lower the volume.

5 ) the other assistant settings are also related to this - they can't be turned off permanently. Any excuse about EU regulations doesn't hold up: other brands have this option on new cars, e.g. under the "Personal settings" item or even using a physical button (e.g. Renault Captur, Dacia Bigster hybrid, etc ), or permanent disabling of either the audible or visual speed alarm (Mazda).

6 ) however, the worst experience is regarding the brightness setting of the (main) display: when the main display switched to night mode for the first time, nothing was visible on it at all, I thought it was broken! Only after searching forums did I find out that although the main display has display settings and therefore brightness in two places(!), it is still of no use, because it is controlled by the small display on the driver's side (https://clubjazz.org/forum/index.php?topic=13902.0). Unbelievable... However, there is no mention of this in the manual. The brightness setting on the driver's side seemed too high to me (at any time of day/night), so I lowered it to 0, and it still "shines" too much. There is a scale of about 20 divisions, I set it to half, but almost nothing was visible on the main display in night mode. Only when I set it to 2 levels from the top (i.e. almost the highest value) on the driver's side and set the main display to full brightness in night mode, it works. But the price for that is that it shines on the driver's side... It is also interesting that the brightness setting on the driver's side has almost no effect on the brightness setting on the main display for daytime mode.

7 ) Even with a large range of brightness settings on the driver's display, I can hardly see any difference between the highest value and 0.

8 ) No applications can be installed, although there is an "application installer". For example, Mapy.com would definitely be better than native navigation, and should work normally on the given system.

9 ) Native navigation - audio instructions, the voice seems to be speaking "from a barrel", there is no way to correct it (bass, treble). Also in Route options - Route preferences - unchecked Toll roads, yet the navigation navigated along a toll highway...

10 ) Impossibility (https://clubjazz.org/forum/index.php?topic=17702.0) delete positions at FM radio

11 ) Is missing automatic car locking (after a certain time interval) if I forget to lock it. /instead there is this weird function/

12) On screen # 7 (but actually on the others as well), the driver's display lacks a simple display of the mode in which the car is currently driving.  On that screen #7, only EV Drive is shown. But all three should be displayed there: EV Drive, Hybrid Drive, Engine direct Drive. 

13) no warning of impending 12V battery discharge

14 ) Some problems with updates

15 ) Opening/closing windows with key feature is only available as a premium feature, although it's not some extra add-on, but just a (pre-programmed) software thing.

16) Auto-Wipers interval (https://clubjazz.org/forum/index.php?topic=17727.msg154397#msg154397)

17) Constant problems (https://clubjazz.org/forum/index.php?topic=17888.msg155322#msg155322) with Android Auto.



What bothers me the most is the "speed alarm"... It's extremely disruptive, extremely annoying. I wouldn't mind the notification on the display, but the terrible sound… If only it could be turned off or at least reduced to a more acceptable level.

Sorry for my English.

100% agree. I don't need the car to tell me I am crossing the middle of the road, I'm looking out of the windscreen

I agree, some Citroens have physical buttons to turn off the lane departure etc so even if mandated to turn on every ignition you can easily override instantly without delving into screen menus and control wheel turning.

I think I’m lucky that my ‘23 Jazz doesn’t do anything too annoying

I have the speed warning but it’s only a visual flashing warning sign and no audible sound so I can choose to ignore it quite easily

All the other warnings I’m also quite happy with as they don’t intrude in every day driving

When I read about this speed alarm I'm glad that my current Jazz will be my last car ever

I've had 56 years of accident free motoring and I reckon I've driven around a million miles

When I moved last year the requirements list was to be within walking distance of a retail park with a major supermarket and a bus stop with frequent buses ....... all achieved

Once all house renovation completed so no tip or DIY runs, car is going as I'm now doing less than 20 miles a month tip/DIY

1) every time the car is turned on, a "Warning" appears on the main display, it's annoying and there's no way to turn it off.
I agree. This warning box also annoys me when I start the car and just want to type an address to the navigation system. It reminds me of those "We use cookies" banners on webpages.

3) I also mind the volume of the turn signals, but there's only the option "high", "medium" and "low", no scale from 0 to 10. I have it on low and it's still quite loud.
I also wish there was a lower than "low" setting. I have it set to low. In slow city driving the turn signal sound annoys me enough that I don't want to leave it on for long periods of time, for example when waiting at traffic lights. However, on a fast, rough and loud motorway that "low" setting can be too quiet, and I can't hear whether my turning signal is on or off. It would be nice if it could automatically become louder when driving fast and quieter when driving slowly.

6) however, the worst experience is regarding the brightness setting of the (main) display: when the main display switched to night mode for the first time, nothing was visible on it at all, I thought it was broken!
I don't like that the main display only has a day mode, and a night mode, and nothing between those two extremes. I wish that the display could gradually adjust the brightness depending on the weather or brightness of the sky. In the evening and morning there can be situations when the day mode is too bright but the night mode is too dim.

The facelift models made in 2023 (in Honda speak: model year 2024) don't have the speed alarm.
Starting with model year 2025 (that is: cars built from spring 2024 forward) did Honda comply with the new EU regulations and introduced the speed alarm.

Like ninanina I own a "pre-speed-alarm" MY24 facelift Jazz Advance built in 2023 and am enjoying it :)

I think the facelift version just before the speed alarm was introduced is the best one to go for which is one of the reasons why I chose mine

However it’s not the manufacturer’s fault introducing these distracting sounds it’s falling in with new EU regulations

ninanina: Of course, but I couldn't choose: Jazz manufactured in November 2024, imported to my country in January 2025, purchased in March 2025.

Well, I guess not all manufacturers take the EU regulations seriously, see the posts above (Renault, Dacia, Citroen...), or is it different?

All manufacturers have to meet the regulations strictly to be able to sell cars in the EU. They have leeway in how to implement switching them off once automatically activated on ignition..

off topic:

I do consider this as a big homage to Honda's engineers if our formost problem is the volume of the turn signal :D
(I could tell you stories about failing exhaust gas recycling valves, faulty high pressure injectors, fraudulent exhaust manipulation measures and generally abismal "quality" at VW - all of which left to be paid by the trusty customers and we are talking here about thousands of pounds worth of repairs...)

back on topic:

I never ever found the turn signal in my MY24 (built 2023) Jazz annoying in any way.
Moreover, my impression is that the displays actually adapt automatically to ambient light conditions without my interfering in any way. I never felt "blinded" by them or unable to see them - they seem to adjust quite quickly even to short tunnels.

Addendum:

The "fine manual" for the MY24 says on page 159:

Brightness
The brightness of the gauge is automatically adjusted depending on the ambient brightness.
 • The brightness dims when the ambient light is dark.
 • The brightness brightens when the ambient light is bright.

You can change the setting even when the ambient lighting is bright, but the brightness of the gauge won’t change.


Title: Re: Software - Jazz's weakest part
Post by: ahavoja on May 26, 2025, 09:43:02 PM
I have to agree with Coldstart about the gauge in front of the driver. I'm happy with how it adjusts its brightness automatically. It's just the larger infotainment / satnav display that sometimes feels too bright or too dim, which makes me want to sometimes adjust it manually. Most of the time it works well, and overall I'm quite happy with the car.

Perhaps I find the turning signal annoying, because the car is otherwise so quiet when sitting at traffic lights without the engine running.

On the touch screen navigate to Vehicle settings > Meter setup > Alarm volume control.
There you can find 3 settings, and they affect the volume of various warning sounds, including the turn signals.

The Jazz user manual says (on page 311) that this setting "Changes volume level of all system warnings, door opening warning and indicator."

OK, reduce the brightness of the driver's display to minimum or half, save it and wait until night falls and "see" what happens.   :D  :(

Stani, I think the speed warnings can be turned off by disabling Traffic Sign Recognition, but needs to be done every time the car is switched on

Yes, that's the only way to cancel that annoying signal - turn it off before every ride.
But you can't have the sound turned off and notifications on the display at the same time.

Another thing - I'm just looking at the manual (p. 312) and it says:
- "Setting the display of the traffic sign recognition system"
- "Warning of the traffic sign recognition system for exceeding the speed limit*"
- "Sound signaling of a change in the speed limit"

But my car doesn't have:  "Warning of the traffic sign recognition system for exceeding the speed limit*"...???

My 23 Crosstar I've had for two months is mildly annoying.

I need two pushes of the button on the steering wheel to get it to show MPG etc.

Then press "brake hold" then three pushes to remove "lane mitigation" and get it back to mpg, before I can move off.
But I have to do this every time I start the car.

It annoyed me the other day.

I backed into our drive and it wouldn't let me put in park, as it said, "I was too close to the side fence!"
so I had to move it out a bit.

I also don't need to be told when it spots a 20mph sign in a side street that I had no intention of turning into,
or a couple of pedestrian up ahead it thinks are too close to the kerb.

I don't understand why it wouldn't let you put it in park

I park in my garage with the nearside just inches from the garage wall and mine goes into P every time

Also, mine has never picked up any side street speed signs. When I first got it I was expecting a few error spots but I've been pleasantly surprised

Re Stani's original post.  Maybe I am too easy going but I havnt changed any alarm sound levels. I am happy to tolerate the default settings . 

The warning display not to fiddle with things whilst driving switches itself off after only 4 seconds.  If you cant bear to wait that long simply press the button.   I think its more annoyance at being repeatedly told something you already know.  >:(  But the next driver may not actually be you. They wouldnt get the warning if you have disabled it.  And unfortunatly experience has shown there are many idiots out there who need to be told such things, even if they chose to ignore the advice.

I find indicator volume about right when travelling at  speed, maybe a little loud when stationary, (when the car is  otherwise silent)  . But tolerable.   

I think you have got it the wrong way round regarding Toll Roads.   Toll roads, vignette roads,  motorways, unpaved roads, U turns etc are all "Avoidances"  .  You tick the box of those you wish to avoid.    Unchecking a box means you are happy to use them.   This is the same on the new  'Here' satnav and the previous Garmin.

Personally I have no issue with the speed alarm. I soon developed  'selective hearing' .  I subconsciously pay attention to the alarm if I inadvertently exceed the limit. The other day the car behind me was a police van, and despite being extra careful to keep to the limit I inadvertently exceeded it by a couple of mph now and again . The beep was as useful warning.   ;D      If I deliberately chose to exceed the limit  (If I think the real limit is actually higher, or occasionally a bit of  :P )  its easy enough to ignore the maximum of  3 beeps which stop once you reach your chosen speed , naughty or not.

Ours picks up EVERY side street speed sign, so keeps on telling us off for driving @29MPH in a 30MPH zone due to the sidestreets being 20MPH

Lord Voltermore: so everything is completely fine, including the fact that if you don't turn the brightness on the driver's side almost to the highest value, then you won't see anything on the main display at night.   ???
You are a lucky man.  ;)

Mr Onion: But yeah, let it be there, but let there be an option to reduce it or turn it off permanently. Let it be an OPTION and not an OBLIGATION.

My experiance [non-Honda] is it get caught out by lower speed limits only where there is a side road with a lower limit on a bend. Nine times out of ten it alerts me for doing anything over 31mph in a 40mph zone due to the side road on the bend being a 30mph limit.

I’ve not had any major problems with the Jazz system as it tends to pick up the correct speed sign

It’s not perfect by any means but most other car manufacturers have the same issue

Post by: Lord Voltermore on June 01, 2025, 12:47:36 PM
My 2021 car used to pick up quite a few 'wrong' speed roundels from side roads etc. I havnt noticed it as much with my 2024 car, which I believe relies more on gps data , but occasionally still happens.
Sorry if this sounds righteous  but  I consider the chimes  as a relatively discrete reminder (once you get used to them )  to double check  you are still correct about the applicable speed limit. Something you should do regularly anyway.       If the legal limit is actually higher there is no big deal continuing to drive  at the higher speed (if safe) as the chimes are not continuous.

 I didnt comment earlier on necessary improvements to adjusting display lighting levels. (TBH being retired most of my driving happens in daylight, although I dont actively avoid the dark  )

When driving I normally have the satnav screen running, even when not needed.  This has automatic night mode based on time and ambient light level sensor  .  Wouldnt this solve  some of the problems of an overbright infotainment screen?

For me, there are two main things that bother me:

the inability to install apps - I would only need to install one - Mapy.com.

The second thing is the speed alarm: if you can't turn it off permanently (which would be best), then at least reduce the volume. Or does the EU regulation also determine the volume level?

For example, I don't mind HERE's speeding warning on my phone. It's just a tapping sound, the tone isn't as annoying as the Honda's.

Stani make sure your Jazz is connected via Bluetooth to your phone successfully; iPhone definitely has CarPlay that works wirelessly, without a cable, but I’m not sure if Android Auto has the same wireless connectivity

I use an iPhone wirelessly using CarPlay and it works a treat

If you have the Mapy.com. app installed on your phone it should show up on the Jazz infotainment screen and you should be able to use it perfectly fine.  Once CarPlay detects your device the Jazz infotainment should show you all the apps on your phone (it mirrors your phone!) that can be used…. I’m guessing Mapy.com should be one of them

Or am I missing something  ;D
Title: Re: Software - Jazz's weakest part
Post by: stani on June 01, 2025, 04:52:15 PM
ninanina: yes, you're missing one thing. :) And that's having Mapy.com installed DIRECTLY in Honda.

Why is there an "application installer" at all if no applications can be installed?...  >:(

Of course, I have Android Auto and I know it, but it's impractical, connecting it with a cable (it doesn't work over wifi on most), having to place the phone somewhere in signal reception, Honda doesn't want to connect with some phones or you have to restart ("triple touch"), etc.

There is an "application installer" in Jazz, but you can't install any applications. Unfortunately, there is no hack (https://www.autohack.org/) either.

I haven't set or changed anything before.

On the next ride, it was back to “normal” (=so the roaring speed alarm).

I haven't set or changed anything before.

Well, at least I had a free ride.   :D

On the next ride, it was back to “normal” (=so the roaring speed alarm).
It means the traffic sign recognition was (temporarily) disabled

This means the detection camera view  is temporarily obstructed and cannot be relied on to be accurate.  Caused by things such as condensation  ,snow , generally dirty or something sudden like a large  insect being splattered on that area of the screen as you drive.

You have to try to remember EXACTLY what symbol it was, stop the car, turn it off before you can access the inbuilt manual.

As others have already pointed out it means that the camera in the top middle of the windscreen has been found to malfunction.
If you are certain, that this area of the windscreen was clean at the relevant time(s), you should talk to your Honda dealership about this, as there might be another more "technical" glitch involved which should be pursued to its root cause!

Then you need to study the EU General Product Safety Regulation which says the warning messages need to be in local language. As not all European languages are supported in the car, then you, as the driver, have to make the decision to turn on.

True , but it is the season when flying insects  tend to splatter the front of moving cars, even if its only just been washed.  Any insect remains within the detection area may disrupt signals  enough that the system shuts down for safety reasons and prompts you to clean the windscreen.  But its not only those soft bodied insects that leave a terrible mess. Hard bodied insects can trigger the warning yet blow away again after a few seconds leaving little or no trace.  Even washer/wipers may not be enough to clear the mess. I often have to  clean  tenacious bug remains off the screen manually during long summer trips.  Less   often in the UK where there  are noticeably  fewer insects , due (IMO)  to over use of  herbicides and pesticides.

I have heard that they don't need to suffer from the speedometer deviation either. Here in EU, because of some regulations, the speedometers of all cars overestimate the speed by a few %.

It would be nice if there was some way in the menu or software to calibrate the speedometer, to make it more accurate.
Title: Re: Software - Jazz's weakest part

My speedo is only 1mph out from my GPS speed.

When I ran a Garmin the displayed GPS speed agreed with my phone and the Jazz speedo was always just one more

Considering my first 8G Civic was about 10% out and my 9G Civic about 6% out, 1mph suits me fine

It would be nice if there was some way in the menu or software to calibrate the speedometer, to make it more accurate.
If drivers had a choice of accuracy most would probably chose 100% accuracy. But then complain if they  get more speeding fines for exceeding the speed limit slightly. I must admit in my Yaris I tended to drive to the speed shown on my standalone satnav rather than the car speedo.   :-[  Living on the edge !  ;D

Cars typically measure speed by road  wheel revolutions. But there is a significant difference between the rolling circumference  of new tyres with 7mm of tread depth and the same tyres when worn down to 3mm. Even new tyres of different brands can vary.   
 It would need to be regularly  recalibrated   perhaps using gps data. Not impossible , but  a speedo based on gps alone  is not legal . It wont  work in tunnels for instance.  So it would need to be a hybrid of both measurement methods.

I was at a Honda service center (https://clubjazz.org/forum/index.php?topic=17716.0) and asked about the software as well.

The technician told me that there was nothing he could do about it, that he had gotten used to the "speed alarm" and that he didn't even notice it anymore.
And for further questions about the software, he sent me to the sales manager.

The sales manager is very disinterested, apparently it's set up that way by Honda and there's nothing they can do about it.
They probably don't even report any user complaints anywhere, they don't solve them...

I think the advances in computer technology has left your "traditional" car dealer behind. Many I guess are still from  the "kicking tyres" era.
To be fair, main dealers have several different models in their showrooms, all may have different software "apps." Added to that will be early models on their show courts with the same again. To be au fait with them all would be asking too much. Their main objective to sell cars to make their monthly bonus. Little time to read car handbooks which most of us find hard to comprehend, or even "find stuff" in them.
If it's faulty, we replace it, no staff around who can "fix computer problems."

I took my two year-old Crosstar in to have the nearside mirror changed today. In March it wouldn't fold in, got stuck half way. Took a video, sent it to the main dealer from whom I bought it, they ordered a new one. In the meantime, I reset the doors and windows. Cured the problem. A couple of weeks later had the same problem with the driver's side mirror, did the same re-set, cured the problem again.  Told the main dealer, suggested they change both, but they refused.
Both mirrors have been working perfectly since then.

Good news, they changed the mirror in less than an hour, whilst I waited.
Bad news, no one could tell me if there was anything wrong with the original. But I've now a "lever" if the other one goes, once it's out of warranty.

I still think it was a software problem. I think computers  are beyond the realms of motor mechanics, it's too big an area, which changes daily.

Where does the "speed alarm" sound actually come from?
I'm thinking of covering that area with some soundproofing tape.
The sound is horrible and cannot be turned down to a tolerable level.
Title: Re: Software - Jazz's weakest part
Post by: ahavoja on July 04, 2025, 05:37:44 PM
@ Stani: I dont know, but it's also possible that the sound could come from one (or more) of the already existing door speakers in Jazz. You could try covering the speakers temporarily, and then go for a test drive, to find out which one of the speakers it is, or is it maybe a separate speaker.

I recommend covering them with some hard and heavy material, because hard materials block and reflect sound back to where it came from much better than soft or lightweight materials. Also tape them air tight so that sound doesn't leak through the gaps.
Title: Re: Software - Jazz's weakest part
Post by: coldstart on July 04, 2025, 06:17:47 PM
Where does the "speed alarm" sound actually come from?

imho the "system sounds" don't come from the regualar speaker system but seem to be generated somewhere within the dashboard (like e.g. the turn signal).

If you should actually happen to find the source please keep in mind that disabling (or at least "muffling") it will also dull other (welcome!) system sounds.

Otherwise consider it a "Zen-exercise" in serenity ;)

Well, I like the the turn signal and do welcome the proximity alert and impending collision warnings!

(remember the days, when we took off at a pointed T-junction craning our necks only to come to an "abrupt" stop in the tailgate of the car in front which somehow "chickened out"?)

Only an acoustic warning can alert you of this situation!  (I've been told the Jazz does "emergency braking" yet am not too keen on relying on it)

I just parked my Jazz and did some listening. Now I am sure that the turn signal and parking sensor beeps are not coming from the regular door speakers. Instead they originate from somewhere in the dashboard, somewhere behind the steering wheel.

Good thing is that they have a separate speaker, which can be muffled without affecting music quality. The tricky part is, how to pull apart the dashboard to get your hands onto that hidden speaker.

I found a photo of the backside of the instrument cluster (https://www.ebay.co.uk/itm/116461781824). There is something that looks like a speaker behind it. I think muffling that could possibly help. There exists a similar looking speaker (https://www.bestartech.com/wp-content/uploads/2022/09/TES01.1837A1-1BDT48-11-08H16-BOX-H%E8%A7%84%E6%A0%BC%E4%B9%A6.pdf), which I found by using Google lens, so I'm quite sure that it indeed is a speaker.

On the jazz dashboard just to the right of the temperature switch there are three slots cut into plastic if you put your ear near to the slots that's where the sound is at its loudest, I used to think they was for pound coins but not now.

I wouldnt attempt to suppress or disable any speaker in this area in case it also  reduces the ability to talk to and hear  an emergency call centre.   

I have no current plans to use this system  but if  the car were upside down at the bottom of a ravine,and I was about to be eaten by a bear , I'd prefer  it to be working.    ;D   Or a more likely scenario ,if I activated it by mistake and the operator tries to talk to me to check I'm Ok,  they might send emergency services if my reply is muffled or absent.

Post by: Lord Voltermore on July 05, 2025, 02:31:42 PM
This assumes  you are still well enough to peel off the tape.  Or you might not  realise  you have  accidentally activated the system( perhaps when cleaning the interior ) If you dont hear the 112  operator at all you wont know to peel the tape off.  If there is any doubt about whether you need help they may send  Police, ambulance and fire/rescue.   

Good luck explaining to the police that their wasted journey was because you  taped  the speaker to stop it annoying you when you break the speed limit ;D    You might not tell them, but they mayl be curious about the system that gave a false alarm which wasnt cancelled. .   

But for those of us who have lived half our adult  life without mobile phones at all, the idea is tempting.

But i found it easier just to learn selective hearing. I hear the bleep when I want it to be a useful overspeed  warning, and I  dont hear it when I dont  . eg because I know the limit is higher or I am deliberately being naughty   :-[

So I was unable to locate the source of the annoying sound from the "speed alarm".
At first I thought it was coming from the emergency call unit. Then the TSR unit logically came out for me (where the rearview mirror is), but it's not there either.
It's coming from somewhere on the right side (left-hand drive), but I don't know where...

Android Auto and Jazz - for those who are interested.

I don't use the installed navigation in Jazz, I already described it in the first post. I use Mapy.com instead (if there is interest, I can create a separate thread for it), because it is simply better, for me the best of all.

However, this can only be used in the Jazz via Android Auto, and this can sometimes be a problem.
Now I was driving and after a while Android Auto dropped out. I tried again, but again a short connection and then a quick disconnect.
Unfortunately, I didn't know the well-known "three-touch" (reboot (https://www.reddit.com/r/AndroidAuto/comments/1fwvquk/howto_reboot_honda_hft_2023_or_newer_to_fix_honda/)) from memory, but even that didn't help later when I printed it out as a guide.
Note: the first time I bought a Jazz and connected my mobile phone, the dealer had to do this "three-touch" check.  ::)

I now have another phone (Samsung) connected to the Jazz with an original Samsung cable. Very surprisingly, it was this cable.
On the contrary, I read on the internet that someone had an extra thick and expensive cable, but it didn't work with Android Auto, they had to use the weak one from Samsung. But it's the opposite for me.
I have now tried 4 different cables and only one works properly: the blue one from Vention.

(https://image.alza.cz/products/VENTf42/VENTf42.jpg?width=800&height=800)

So it could be the cable, but I'll also describe other pitfalls.

The most secure connection with Android Auto is via a USB cable.
Set the following on your mobile:

In the Android Auto app, click on "Version" at the bottom, then click on "Version information" 10 times and enable "Developer settings".
Then click on "Developer settings" at the top in the settings (three dots).
Uncheck "Android Auto Wireless" and then check "Unknown Sources".
Then again at the top of the settings we can select "Exit developer mode", the previous settings will be retained.
To be on the safe side, set AVRCP 1.4 (https://clubjazz.org/forum/index.php?topic=17538.0) on your mobile phone (because the Jazz has an outdated OS - 8.1).

Obviously there must be variations among every phone on the market, but I've never had a problem with Android Auto on 2 Samsungs, maps or music. Bought a 6 inch right angle usb cable to suit the dash on ePrey years ago and it just works, never need to charge the phone at home because the car does enough for me. The odd occasion the map blacked out, it was back in a couple of minutes after an automatic update.

For the driver's display, most people probably use screen no. 7.

Unfortunately, the driving mode is not shown sufficiently here: there is only "EV" - when it is lit, the drive is purely electric, the combustion engine is not running.

When it's off, the combustion engine is running. But I'm missing an icon, an inscription, when the combustion engine switches to direct drive.

I know, you can find out on screen no. 4, but who has it permanently turned on.

So we were dealing with the 'speed alarm' together with my good electrician and the Honda technician. They spent over an hour going through the wiring diagram, but it didn't help.

Most likely, the same speaker for the "speed alarm" is also for the proximity sensors.
Therefore, even simply reducing the volume by damping it with some material would be counterproductive.

So the only option left is for Honda itself to do it with a software update. Which unfortunately probably won't happen...  :(

Believe me, some things on my 2021 model, lovely car that it was overall, from a software perspective were substandard. 

On my 2025 model, nearly EVERYTHING has been improved, some things, just a little bit, other things are night and day.  Two examples, huge improvement to response to infotainment screen finger presses.  Useful improvement to smoothness of adaptive cruise control, modest improvement to accuracy of DTE mileage countdown.

Well, you will probably get the "weed-grower of the month" award next :D

imho this just means, that you made your trips with a light right foot.

I'm afraid it's 0 - the three rectangles at the bottom must be filled in. I have half of the first one filled in (with a mileage of 1300 km).

Yes, the three rectangles are filled in. My total mileage is 6300 and the system shows average consumption of 62 mpg, so true consumption is around 60 mpg. I don’t think that is unusual or worthy of a coconut, but I could dangle it in the rear window I suppose!

Now an ad has appeared: "permanently disabling the traffic sign recognition system (https://1url.cz/nJSIj)"...
I think it's just something like a way to cover the camera...
Which may have an effect on disabling other assistants connected to the camera, I think.

What a "brilliant" idea indeed!
(I find some of the camera-based assistants quite helpful!)

One of the problems with the "speed bongs" is bad road signs. In Switzerland there are no "exit-only" additions to motorway exit speed limitations (which the Jazz - imho correctly - then interprets as the "regular" speed limit.

Another of my "favourites" is the infamous "zone sign" (again: not complying with regulations!) where the crossbars don't go smack through the middle.

I have reported this to the "authorities" - alas, they don't seem to give a f*** :(

Great idea turning all the safety features off but have an accident and wave bye-bye to your insurance claim, "Oh just give me a minute officer while I remove the gaffer tape from the safety camaras"  ::)

I'm not sure if that's the case (camera cover), I'm just assuming. Because hacking (https://www.autohack.org/) newer Hondas is probably no longer possible.

Something I found out about my 23reg Crosstar  today. After turning off the car, I was in my golf club car park and getting my gear out of the back and I happened to let the top part of the bag that holds my electric trolley drape over one of the rear sensors. "It told me it didn't like it."

I dont think simply putting a piece of tape over the traffic sign recognition  sensor would silence the speed bongs. The system uses a combination  of  gps location ,based on whatever speed has been input on the mapping, plus sign recognition if this is different and may be correct.    But mapping may been input incorrectly or out of date and sign recognition is not infallible.

If a glitch whilst updating  satnav maps has silenced the bongs does this not mean that  satnav is fundamental to the bong system? Any hack to silence the speed alarm would  also have to hack into the satnav.  Rather you than me. 

I dont see why anyone would want to silence a system that warns them they may be putting lives at greater risk  or breaking the law.   So what if it bongs at an indicated 30 mph when in reality you are only doing 27 mph? The speed limit is a maximum ,not a target. And if you want to take your full  actual speed  quota   by exceeding your speedometer reading by a few mph  (or more )   then simply ignore a few bongs .  Its quite easy to develop selective hearing.  ;D

  Unfortunately most drivers  believe they, and their car,  are competent enough to quite safely exceed the speed limit  . Especially young inexperienced males.  The biggest lessons I learned  from taking an advanced driving course  was that nobody is ever as good as they think they are , and  that the safe speed for the  circumstances is often much lower than the applicable speed limit.  (or much higher for a great driver like me    :P  ;)  ;D )   Other opinions are available  ;D

Sometimes I give a commentary (in my head) as I'm driving stating what possible hazards I can see, what car is behind me, what I anticipate might happen, etc., I think it improves my, "road craft."

The audible "speed alarm" is (at least for me) a terribly annoying thing. I drive mostly in the city - where it is not worth turning it off before every ride, but at the same time it sounds very often.
Until recently, all drivers drove without this "convenience" and what, was it worse on the roads?
Title: Re: Software - Jazz's weakest part

Oh, I just saw that something new appeared in the ad:

I would like to point out that it has 2 victims:

1. The car will not recognize any speed limit sign (see photo)
2. You will have to do without integrated navigation. So only Apple Carplay or Android Auto, where you will get a better basis anyway.


So it's probably not about covering up the camera. And now I'll speculate a little: in the previous navigation in Jazz it was (supposedly) possible to stop navigation in the hidden menu. This is no longer possible in the current version - I tried it. Maybe the tech guy figured out how to end the navigation after all.
And since navigation in the latest version of Jazz is most likely directly linked to the speed limit, its termination also means the end of speed limit warnings.
But as I write, it's just my opinion.

Yes, it was worse. The safety trend is slowly improving in the UK.

For those who are interested: I contacted the person from the ad who updated it. From this I deduce that it is not a case of sticking the camera over it :-) (I have already read about that) - which would be wrong, because other assistants also use the camera.

He writes that "You will have to do without integrated navigation"...

I know that in the first version of the Jazz e:HEV it was possible to deactivate the navigation in a hidden menu. In the second, FL version, this is no longer possible. Or, as I am not the only one, I deduce that the navigation is already firmly connected to the speed limit.
Edit: I actually have it confirmed. I drive through a bypass (https://clubjazz.org/forum/index.php?topic=17927.msg153809#msg153809) that the built-in navigation has not yet loaded and there the traffic sign tracking always disappears and therefore the speed limit warning is also not functional.

So there are two possibilities: that he came up with some trick to (permanently) deactivate the navigation and the associated speed limit warning.
Or deactivating the GPS signal and the associated non-functioning of the navigation and the associated speed limit warning.
The second case would not be good - because other functions are connected to the GPS - e.g. e:Call.

And he replied that this is the first case where the GPS data will continue to work.
And that it is not in a hidden menu as I thought.
Of course he does not want to tell me more.
Another thing is that if you do a factory reset, then it will come back again.

Well, I decided to go for it, and hopefully I will have it tomorrow afternoon.

I think what happens on my driveway confirms the system is heavily reliant on gps  data. Even though its only a distance of about 5 metres the satnav shows I have driven off road with a 'breadcrumbs' trail and the drivers display shows a greyed out 3 dot symbol.  It changes back to 30 mph as soon as I return to the highway even though there are no 30 mph signs displayed that  it could have recognised.       

I'll have to ask my Chauffer what happens on the 2km private road to "Voltermore Castle"   ;)  ;D 

Each to there own but there is no way I will hack the system. I wouldnt turn it off even if there was a legitimate  on/off menu option.

I am probably repeating myself  but  I find it  helpful   being discretely  bonged if I inadvertently drift over  the speed limit .A useful for road safety and avoiding speeding fines.   If I chose to  defy the warnings ,if for instance I think it is wrong about the applicable speed limit, or I want to drive at a 'true' 70 mph by having 74 mph on the speedo  , I simply use selective hearing.  I will hear and react to an unexpected bong,  but easily ignore  expected ones.  They are not continuous and not IMO excessively intrusive.

Is it such a bad thing to have the occasional  bong if it makes you think , look around, and reassess whether your speed is currently  appropriate for the circumstances?   

The following is a bit contentious.  Sorry in advance.  Its  not  personal or directed at anyone in particular.
 Be  honest with yourself. Is it the sound of the bongs  that particularly annoys you  (some people  are genuinely more sensitive to certain sounds than others ) Or do you dislike having your personal  freedom monitored and 'criticised' by a machine (or the police' ;)) ,  Or  are you getting more than your fair share of bongs because you may not realise  you habitually drive a bit too fast?

Everyone has a different opinion, different preferences.

I've driven my whole life without this annoying sound and without accidents.

Yes, and it's about this terrible sound. And unfortunately, it is heard often in the city.
As long as traffic is flowing smoothly (in a larger city), there is no other way, and these are not major speeding violations, quite the opposite.
Everyone who rode with me in the Jazz now wondered about this annoying and moreover recurring sound.

I have nothing against speeding warnings in principle.  Before Jazz, I used external navigation (Mapy.com, Here We Go) and so I turned on the speed warning myself. Because it was not only a decent sound, but most importantly, MY CHOICE. 
With Jazz, you can't just turn the sound off or mute it. It's NOT a CHOICE here. It's forced on me here.

I wouldn't mind, or even like it, if it were like before spring 2024 - that is, only a visual warning about speeding. And those who have a Jazz before spring 2024 are certainly not deprived of anything and are not worse drivers.

I think you should be able to  turn the volume of the speed warning down, like you can with sound of the indicators.
Title: Re: Software - Jazz's weakest part

So done.  ;)

The guy arrived and it was done in a moment.
Of course, I couldn't watch how he did it exactly, it was his secret and I accepted it.
I could stand outside and watch him not connect anything. All he needed was his hands and his cell phone, which he was reading something from. He only worked on the main display, which he covered with his hand.
The whole thing took about 30 seconds.

Afterwards I was able to test that it was permanent.
It doesn't mind a reboot (I tried it myself), or even a software update.
What bothers is the factory reset - then it's erased and everything goes back.

The most interesting thing is that the internal navigation has completely disappeared from the main display menu, it is simply not there anymore.
Also, the traffic sign icon is not gray (this is in case sign tracking is always turned off before driving), but is now orange.

He's already done it on the ZR-V, CR-V and Jazz.
Title: Re: Software - Jazz's weakest part
Post by: Lord Voltermore on November 17, 2025, 09:25:59 AM
I can see that if heavy traffic is flowing smoothly  everyone may be travelling slightly over the speed limit  ,either in reality, or as  indicated on  speedometers that tend to read  slightly low. Its tempting to 'go with the flow' and indeed  driving slower than everyone else may increase danger by causing disruption to the majority of traffic. Yes you may get lots of annoying beeps. Either from the alarm, or  annoyed drivers sounding their horn.   ;D

But this hack seems drastic to me, and in the UK at least would probably be illegal. It would probably also make your insurance invalid.  Insurers would not allow a modification  that allows you to exceed the speed limit without annoyance.

The fact the light goes orange is a fairly obvious indication  there is a fault  with a legally required safety system.  And it  may be  recorded historically   in the telemetry of fault codes etc  , even if you reset the system  before anyone 'finds out'.    Eg in the event of a serious crash the police may examine the cars condition for safety features  and Insurers may do so  in the  hope of refusing your claim.This may be before you can reset the system. 

 The orange light would probably result in failing an 'MOT' technical  test in the UK  .(If such hacks become common  testers will be alerted to watch out for it. ) 
Also if the car goes in for a service with the fault showing they may do a factory reset to fix it ,even if you ask them not to. And may charge you for the repair.  (there may be moral or legal reasons why they cannot just ignore it ) .
And dont forget to  factory reset before you sell the car. 

Ultimately its your choice. I am just pointing out some of the possible  problems to anyone  tempted to use this modification.

This morning I contacted Honda dealer Karlik in Poznań (Poland) and asked them if they were aware of the "secret" method for turning off speed limit warnings for Honda cars and sent them this picture
(https://clubjazz.org/forum/index.php?action=dlattach;topic=17635.0;attach=12464;image)
plus this link: https://auto-bazos-cz.translate.goog/inzerat/209751566/vypnuti-systemu-rozpoznavani-znacek-pro-nove-vozy-honda.php?_x_tr_sl=cs&_x_tr_tl=en&_x_tr_hl=cs&_x_tr_pto=wapp

Half an hour ago, I received a call back from the technical maintenance manager, who told me that this is a trick well-known to many Honda technicians. It can be done within a minute.. It is consistently NOT used by Honda dealers because it's illegal and will cause (major) problems. If not with the law, then certainly with insurance companies in the event of an accident, he emphasized. In addition, your navigation will no longer work.
He jokingly wondered if a Czech (ex-?) Honda mechanic earns some extra money this illegal way...

Kremmen: I asked him about it and here is the answer: the restriction only applies to the built-in navigation, which is not functional and will disappear from the menu. If you mean "Google linked via bluetooth" - Android Auto/Car Play via mobile, then it will work normally.

After disabling the terrible sound (https://clubjazz.org/forum/index.php?topic=18015.0) and riding without it for 2 months, I can say: a big relief....

Yes, it has one major drawback - completely disabled internal Navigation and a problem with Android Auto (https://clubjazz.org/forum/index.php?topic=17888.msg155908#msg155908) (but there have been problems with it before and there will probably always be some). But it's worth it. I can't imagine driving it again. 

Apparently I finally figured out the trick (this is not a “hack”) to permanently turn off the sound notification (it can be reverted). It's easy, it's done in 1 minute. If anyone is interested, send me a private message here and I’ll give you the instructions (I don’t want anything for it).
