Has any body had this message and a subsequent update installation occurring?
I don’t know what this update was for or how it was input, I accepted the option to install once the engine was off and then it was a success message followed by a check map update prompt (yet to do)
Seems a bit wierd!?
Any feedback back or explanation would be greatly appreciated, thanks in advance.

Dave is yours the same issue as in this post? https://clubjazz.org/forum/index.php?topic=17766.0
-
Yes, I think it is probably is the same update issue.
I had previously set up the Jazz to connect to our home WiFi (which is a good connection on our driveway) when we first got the car over 4 years ago now!!
We’ve never used that WiFi connection to achieve anything since but appears that this update has landed via that WiFi connection.
Be interesting to see what the update is actually for as someone is enquiring on the posting you have highlighted.
Thanks

I just tried updating via USB drive, but it said: "Vehicle is updated". Jazz Elegance manufactured in November 2024.
-
I updated using my home WiFi. All it did was download a user handbook update, never ever read the on board manual, so a bit of a waste of time.
-
I have absolutely no clue what my update was for as it didn’t mention anything about it
I just downloaded it and installed it, after 3 attempts. I can’t see what’s been updated as yet
Really annoying that my iPhone lost connectivity after the update so had to reinstall the phone; all working fine again now

Is your Jazz an Advance manufactured in 2023 with Garmin navigation?
Still no update for mine.

If you go into the system updates app and select the settings button, then look at update history it will list the update items relevant to the update completed.

The update history is showing in parallel topic number: 17766.0

It all seems a bit hit and miss.
My 2023 Crosstar when it's on our drive can't find the router in our house. So I attempted to do an update using a USB. I used the one with all my "car music" on it as there was room. I attempted to download any updates and the site said it could take up to ten minutes. I gave it twenty and it was still uploading! So I called it a day. I also deleted the Honda update connection file.
This was over a week ago.
I was sitting in my car in Sainsbury's car park the other day, with the engine running and the radio on. All of a sudden, a message flashed onto the screen which said it was doing an update. It was over in a few seconds.
Amongst my many music files and playlists, on the USB I have in the car, I noticed this morning there was a file that said "Garmin." Maybe that was used for the update?
In the meantime I'd ordered another Sandisk, they are only seven quid. So tried another upload using this as a dedicated USB.
I did this yesterday and it worked, well, it said the car's software was up to date!
-
I have just had the update notification, in a way that I haven't seen before. Normally it is the little open map icon that appears on the navigation screen... this time it was on the start up page as a little orange disc with a 1 in it.
Selected it, and it told me it was an audio update. Pressed the button to off as instructed, it told me that would be when the download would start.
An hour later I sat in the car, turned the ignition on and after the screen came on, it told me the update was complete. The screen was black for longer than normal though at first.
All seems fine.
I must point out that I park on my driveway in front of my front room window, and about 10' from my router. It shows a good strength signal on the consul icon.
-
My problem is that I park my car in front of our house on our drive which is to the right side. The router is in the opposite corner of the house behind the lounge French window curtains as far away as it can be!

You could try a range extender. Even if it doesnt work well enough to reach the car it might justify its cost by improving wifi reception elsewhere in the house. here is a cheap example from Argos.
https://www.argos.co.uk/product/1115138?clickPR=plp:1:6
Also you can download various free apps to your phone that measure the strength of wifi signals. These are helpful in optimising how you position your router, or an extender , or the car, or indeed you might decide you need a better router. You might for instance find the car gets a stronger wifi signal at the bottom of the drive, or in the road than it does closer to the house.
-
Not a fan of range extenders as they mean a second SSID address and maybe a manual device change is needed
A mesh system, IMO, is far better and what I've got
A mesh is the same SSID and as you move about your device accesses via the strongest signal
-
Yeah sorry, my idea is a bit outdated . I did use a range extender for a while but it was no longerr needed when I got a better router. Maybe download an app first and measure your wifi signal strength at various places within and around your house and experiment to see if these can be improved just by repositioning the Router.Even a slight movement in its orientation, or its aerial(s ) can make a difference. You may find you dont need to invest in other solutions.
-
Lord V and others.
I live in a house brick built in 1949/1950. The internal walls are blue 'breeze block with plaster. The wi-fi from my single router is very patchy (Excellent > Poor) as I move round the house. :'(
When I needed an iternet connection in my MK 3, managed to extend the telephone cable enough to locate the router on front door step!
The other option would have been to set Android 9 mobile phone up as a hot spot and get the internet connection from a local tower.
-
In your case I would suggest PowerLine adapters
They push data through your electrical wiring so avoiding brick walls and other hinderences

I use a mesh system throughout the house; main in the lounge, one in the kitchen and one in the shed outside
I use this: TP-Link Deco M4 Whole Home Mesh WiFi … 3 pack
It’s worked perfectly for about three years and gives WiFi to the bottom of the garden with no problem as well as out on the street
I found range extenders absolutely useless
-
Another vote for the TP link Deco M4 mesh system
-
My parents used a TP Link system for many years, I don't know what model it was. It worked well.
-
I have one TP link plug-in range extender unit which works well. Gadgets switch easily between router and extender. However, it doesn’t help with the car which is parked 50 yards away!
-
Did my update today, worked well connecting to home wi-fi via TP-link Deco Mesh.
Took less than 10 mins.
-
I’ve just done a HERE map update by parking the car outside the flat to use the router. I tried 3 UK regions. The downloads of the first two just took a couple of minutes each, but the subsequent updates took more like 10 mins each. The third download got stuck on 1% and I gave up. It was for the north and Scotland so perhaps it spotted I am a Sassenach! I might try the USB method next time.
-
Ah, so this is what is was?!
Yesterday I drove a short distance to Aldi, I had my hotspot on cos my wife was using it for her phone, so the car was also connected to it.
When back to the car after shopping, the screen was off and buttons not lit up so I tried restarting the car. Then the screen showed the "System update completed" message.
From there it was a nightmare as the Google maps and Waze navigation were broken, it would not find a route or if connected the phone after starting the route, it would cancel the navigation within 15 seconds.
I had to find a video on how to access a diagnostics mode to do a system reboot, luckily that fixed it.
Very hit and miss from Honda

So this is what our world has finally come to?
We are unable to find our way home even from "a short distance to Aldi"?
Humankind is so doomed! ... (where's this "facepalm" emoji?)
on a more sincere vibe:
I do hope, that you are aware, that you are delivering yourself to the whims of the "Orange" (or whomever) if you let your "thinking" be done by any (american) online service?

I have always updated my satnav for full maps using USB stick. I format the stick before the procedure and never had any problems. The procedure is basically the same for both Garmin and Here (except for "here" I also had to download their equivalent of Garmin express) IIRC 'Here' requires much more free memory on the stick than Garmin did , which suggests their maps use more data.

To be fair to JamXRS, at no point does he mention "home" as either his point of origin or his destination. It's entirely possible that he's staying at a holiday location and doesn't know the local roads, or that he's going on somewhere after doing the shopping.

My 23 reg. Crosstar tells me that Updates are available. It can find half a dozen routers, but not mine.
I tried the USB update method, but the site says "no updates available."
What's going on?
It's done this twice in three days now.
-

How can it notify you that updates are available when you are not connected to the internet?
-
You have a choice.
If it won't connect to the internet, you put a USB stick in the socket and it automatically uploads a link.
It tell you to put this in your computer and click on the link. Honda finds the connection and asks you where you want the update sent. You click on the file the car provided. It is then supposed to download any updates available. In my case it says there aren't any. But why is my car saying there are?

The Garmin based headunits used to give a similar message after a year, maybe it's just a heads up that there may be one ?

Thanks for the very clear and logical explanation. ;)

Firstly: I am a technophobe,and don’t mind admitting it!
Secondly: I have this little orange disc and when I touch it I am expected to touch ‘install updates’,or whatever it says,then switch off engine.
Ok I’ve done this and nothing,nowt,diddly squat happened.
My question,or should I say,observation is: this doesn’t work from a phones mobile data then? So from what I have read I have to connect to my wi fi at home? Correct?
And if that is the case can someone please guide me through the steps to connect my wi fi at home to my infotainment thingybob..
Thanks so much for reading this nonsense,sorry that I haven’t a clue. Never had this type of stuff in previous cars.
Grrrr I hate technology. My radio and cd player in old Jazz were great!
-
And if that is the case can someone please guide me through the steps to connect my wi fi at home to my infotainment thingybob..
General settings/connections/wifi/change mode/network
Then look for your home WiFi network and select it. It may take a little time to say “connected”.
All rather tedious!

Thank you so much for a swift reply. Sounds tedious,but is it really worth it? :o
-
You will need to do it if you want to update some of your maps. Or you can update all of them using a USB disc, but this is even more tedious - it took me 40 mins to download from my laptop and another 40 mins to upload to the car.
-

I’m new to Jazz ownership so may have got the wrong end of the stick, but I wonder if it uses the embedded SIM that it uses for the e-call feature?

Just testing. I typed out a post like this,but it wouldn’t ‘post’. Are we only allowed so many letters. Grrrr . Nor could I post an image. It said ‘too large’…it’s only a smartphone pic of my dashboard..
-
Well that posted. Will try again…anyone else have probs posting?
-
This is a screenshot of my post. This worked but wouldn’t attach to my long post haha
-
This is the screenshot
-
Apparently I have to delete the phone connection in the pic above and input my home WiFi details……or is there a way to ‘add’ my home WiFi details so I don’t then need to delete my phone connection..
-
I always had my phone connected by Bluetooth only, what advantage does a WiFi connection give you ?
-
Jazzfreak - Go to general settings/connections/wifi and change mode from smartphone to network. Then look for the network you want to link to. It helps to be patient!

Patience? Lost that a long time ago ;D
Thanks for reading my diatribe anyway. I will consider updating when I’ve cooled down and then to bring the car into the living room for a good connection. Partner will be thrilled ;D

Jazz Mk 4 Hybrid 2024: I have software updates available and have installed a (home) Wifi connection which doesn't seem to connect (reception issue maybe ?), and I do not have a suitable mobile phone.
So I purchased a 128GB USB memory stick to try the alternative route ('How to Update with a USB Device', manual p.269), but see "Error The connected device does not contain any files that can be played on this system ..", screen shots attached.
The USB memory stick can be read on a Win 10 PC, and I am aware of the guidance, "A FAT32-formatted USB device between 8GB and 32GB in size with at least 8GB of free space is recommended."
Is 128GB an issue ?
Or is it best to let the Honda dealer sort out the software updates at my next service ?
-
When you say you have established a home WiFi connection which doesn’t seem to connect, have you been into general settings/connections/network and scrolled through the available networks ( it may take a minute or so)? If you can select your home WiFi it should then ask for the password.

Many thanks - yes (Plusnet system), and the password seems to have been accepted.
-
Is your home WiFi 2.4Ghz or 5.0Ghz. The car will only detect 2.4Ghz WiFi.

Many thanks - interesting point. The hub is dual 2.4 GHz / 5 GHz. The TV and the TV recorder seem to be using 2.4 GHz.
-
I've mentioned this before. My car a 23reg crosstar can't find my Internet hub as it's in the corner of our lounge at the back of the house and I can't get the car far enough up our drive for it to find it. The software says there are updates. I insert a USB stick in the car and it downloads the link. I put this in my laptop, click on the link, it connects and it then tells me that there are no new updates and my car is up to date. This has happened several times over the past four months.
I've given up with it as the car runs fine.

When it accepts the password and you try to connect, does it say”trying to connect” or connected”, and do you get the fan symbol in the status bar along the top of the screen?

Windows will format a 128 stick as exFat as default, and the manual says it needs a Fat32 stick to read. You need a special program to format your 128 stick as Fat32 in Windows, Fat32 format (google it) is a free program that can do it. Otherwise a 32G stick is the largest size that Windows will allow to format as Fat32.

Update - I've tried a 32 GB memory stick, but encounter the previous error message, details attached.
I'm going to leave this issue until the next service in a couple of months' time.
-
I had a similar message once and after reading the online Honda instructions closer I reformatted the USB stick using the 'default allocation units' option and it worked

The only other thing is try a newer USB stick, assuming yours isn't a new 3.0 one
I first used an old stick I'd been using in my 2013 Civic and that failed to be read
Then I got a newer USB and all well
Just looked up the one I bought ..... SanDisk black 16b 3.0 flash drive
-
So today I finally managed to update the software via USB-web (when I tried it in the summer, it kept loading on the web for a long time, until it froze and nothing).
The update is called "rb_update_1763377981231" and it also solves Android Auto and Apple Car.

Hello,
my experience: as a new Jazz user (crossstar 2025), first thing I tried was to update what I could (maps and system sw ).
I had the same message as per your 1st screenshot; I am using a mobile phone (android) in hotspot mode to get the data.
I declined the update with engine off, and did it on the spot. What happened next is:
1. It took some time to do the update (I thought it would be faster)
2. It confirmed the update was completed and it rebooted. Reboot was also rather slow
3. Upon startup, the navigation apps, embedded garmin and the android auto would not start (garmin would refuse to start, android would be unable to accept any route :( ) . Radio FM/Dab and other apps ok though.
4. To recover, I had to reset the system (option under 'Systems' menu). This also was rather time consuming
4.1 Upon restart, I had lost my personalization (radio stations, saved places in garmin, etc), so I had to reenter these; on the positive, it seems the system did update :)
Bye, bye
Giovanni

Mine just did two updates via the TCU and my home fibre broadband. Mostly Android related I believe. Anyone done theirs and was anything noticeably different? I haven't noticed anything yet but was hoping for wireless Android Auto - it didn't happen.
-
Wireless can be activated via the engineering menu as posted here a few times
But, I found the Google version very hit and miss so went back to cable. Can't comment on CarPlay
-
Having new house and new house in September I connected to my full fibre broadband and updated software in seconds.

A very strange thing happened to my Jazz yesterday….
For some time I kept getting reminders about a software update. I have been ignoring it because it was such a faff trying to work out how to do it and connecting to the internet. Even a chap at a dealership attempted to show me how it was done…but I found it a bit technical (yes,I am a certain age ;D)…
Anyway,others on here said it wouldn’t make much difference so I left it…….THEN yesterday ,nowhere near home or a known internet connection…a message on the screen …”Your software will update in 1 minute”..I didn’t have time to wait,so switched off the engine… 2 hours later returned to the car,switched on and a new message “Your software has been updated”…
Is this witchcraft? Work of the devil? Who knows? But I am just a little confused,but happy…..
Anybody else have this ?
-
I've had a similar problem.
I've a 23reg Crosstar. It can't find our internet hub when the car is on our drive. So I have used the USB method several times as it says there's updated available. When I go on-line it says my car is up to date.
I was once in Sainsbury's car park and it automatically updated, "something."
It's due for a service at the beginning of next month, I'll let the main dealer sort it out.

I had the identical thing as you described happen to me about two weeks ago
I just thought oh well that's good, strange can't weigh it up, although the wife has a few
things that do automatic updates, laptop iPhone iPad all apple devices if that makes
any difference. I like you ignored all the update available messages then it happened.
-
I've a message on the big screen that says a software update is available.
My car can't access our internet hub as it's too far away to connect.
I've used a USB, but the internet site says "there's no updates to download."
It's been doing this for a year.
The car's going in for a service on Monday, I'll let them sort it out.

Just a heads up……for those of us with the older Garmin Sat Nav systems the latest map update for 2026 is now available
