Buying a used one is not good…. They are out there because the prior owners gave up. Remember CarFax lies. Fingers crossed you didn’t just buy someone else’s headache. (Dealer can run prior service records for you)

Not necessarily. I traded mine after a year for a 2023 model with more options because I loved it. . Mine was perfect. So someone else got a great vehicle at a good price.

I just picked up my 2023 Wagoneer III and immediately hit the maps /TomTom rebooting, switching screens, etc..

Downloaded the update (16.7) gig .zip file and unzipped to an NTSF thumb drive. The zip contained 8 files.
Started the wagoneer and brought up the maps in the infotainment center, then inserted the USB. A dialog came up and recognized a new update. Took about 20 minutes to update. All seems to work well now...

Where did you get the update? I have this problem now and its really annoying esp since I drive a lot for work and use the Nav to get to where I need to.

I am happy so say No more TomTom Reboots!!! I’m so glad everything is working as expected now!!!

What did you end up doing that fixed the issue?

What did you end up doing that fixed the issue?

I downloaded the new North American Map from the Stellantis websit onto a USB I believe formatted to NTFS and it auto downloaded and updated. I had to leave the car run for 30 minutes or so...this fixed it. I posted details somewhere on this site. I can get the details again if you need it. Adrian

Snagged a 22 WG series 3 and ran into a problems with UConnect right off the bat. Connecting to Android Auto/Carplay was a battle, only to be followed by a new dance of disconnects every 10 minutes or so after an update. After a few rounds with the service team, they've decided to bring in the big guns and replace the radio. Shoutout to my service manager for being a champ! Here's hoping this move nails it. Countdown to installation day: 9 days. Stay tuned, and keep those fingers crossed for me.

Sorry you bought a used headache.

Oh, my gosh! It’s not the radio, these dealers don’t even read their own service procedures (TSB).

You need a software update to the radio, then a map update to 7/23.. so frigging simple

If you want back up search this forum, right down all the TSB info. March I yo the service manager and say “do this please”.

Sadly your now in the love hate relationship and it’s an expensive divorce given your limited rights with a used car.

My 2022 is doing this, and I've had it in twice. So annoying and dangerous. Anyone have a fix yet?

Yes - scroll up in this forum for instructions

Earlier, I shared that I was waiting for a full replacement of my radio unit after many rounds of software updates at the dealership and attempts to update the Tom Tom maps via USB. Here’s an update now: For the past 40 days, my infotainment system has been completely replaced, and I'm happy to report no issues with Android Auto disconnecting. The reason I'm confident is cuz before the replacement, navigation, android auto disconnects resets every 5 mins. My service advisor turned out to be a hidden gem. I want to stress that I tried every tip the forum recommended, but in the end, replacing the unit was the only solution that worked.

I purchased my 2023 JGW -S3. Mine is currently at dealer awaiting programmers update. This was a leftover 2023 “Rescue”. Same deal and I forgot to take a photo is software version before sending off to dealer. Last update was they were retesting a couple of modules but sounding like one or possibly more modules. I have had this before with other vehicles and turned out to be modules. I was initially thinking the screen itself, but now not so sure. Rebooting was getting annoying because it would reboot with NAV and an active route in progress. Ironically the reboot was on my way back to selling dealer for the wheel swap causing a couple of misssd turns. the build date of the problem vehicle was 3/31/23. The previous vehicle was 2023 Wagoneer S3 and didn’t have the issue. My suspicion is a “bad batch” but unsure of what production dates are affected. I was also informed that there is a thermostat recall. The new thermostat arrived yesterday and dealer is trying to work the thermostat recall while awaiting the UC programmers. besides that great vehicle and definitely has luxury and performance. I also suspect the transition from Garnin to Tom-Tom is a factor to a certain point. I had a two 2022+ JGC-L’s and this is second JW/JGW…..this is the first UC5 issue. No issues on my 22 Charger with UC-4 NAV…..(Garmin….just saying) UC-5 overall is a decent system. Even with this reboot issue still easier to use and the clarity of the screen is much better. Granted the screen size upgrade from 8.4 to 10 and 12” is also a factor. It is nice to be able to enter entire address as one entry instead of keep having to “drill down” into state, city, street, number etc…. I actually feel like I am slimming going back to the Charger….NAV mode wise.

Your problem is software . Dealer updates informant then maps. It does not work OTA due to file size. There is a TSB on this known issue.
