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    But mapping may been input incorrectly or out of date and sign recognition is not infallible.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?

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 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.

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.

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
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...

Is this just the built in navigation that stops working or does it affect Google linked via bluetooth ?
Let's be careful out there !

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.
