What is the TBS? I just bought a new Wagoneer and my Tom Tom reboots every 5 minutes. Agree super annoying. Any recommendations. Brought it to the service Dept on day 3 of owning and they were no help.

I am a new Jeep Grand Cherokee 4Xe (11/20/2023) and the TomTom did not work right from day one. Same problem of rebooting every 5 to 7 minutes and wiping out any route programmed into the navigation. Dealership is clueless how to fix the problem, and they act like I am the only one who has ever reported the issue.

Really simple to fix - all the notes are above

Hi all! I have a 2023 Grand Wagoneer and the Navigation keeps restarting. Same issue as our 2021 Grand Cherokee L Summit Reserve. What is causing this? Software version is FCA-MY23.T25.50-PROD. It is getting really annoying on trips to say the least. It’s like no one knows exactly what is going on or has any remedy to fix these weird issues. Have tried factory resetting and that didn’t help. Tried just using Bluetooth instead of CarPlay. Issue persists. I know many people are having the same issues. What gives? Doesn’t make sense. I also have a 2019 RAM Limited. Doesn’t have any issues like this.

We also have a 2023 Grand Waggoner and dealership is at a lost. I’m really getting upset that at the price point we are dealing what with seems like an easy fix.

What is the latest software version so I know I'll have it when they do the update? Or so that I can check to see if I already have it? I just bought mine the other day and am experiencing the reboot issue. I have just downloaded the maps and am going to install those tomorrow. But I haven't made a dealer appt yet in case I already have latest version.

My TomTom and infotainment system has been great since the updates. But now my engine is locked up. It was fun while it lasted.(Less than 4 months) What a PoS.

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)

I successfully updated the TomTom maps on my 2023 Jeep Grand Cherokee. USB stick formatted to NTFS. Downloaded and copied the 8 items in the folder to the stick. Turned on the Jeep, opened the Nav app. Opened Settings. When I initially opened the Other folder, I did not see any way to load the new maps, but as soon as I inserted the USB stick, a dialog box opened asking if I wanted to install the new maps. Clicked OK, and the total install took about 30 minutes. No more TomTom reboots.

Oh mines not used. Brand new. Just didn’t know what the latest infotainment software version is the latest.

Informant version is under settings…. Map update is available for down load (search this sit there a bunch of posts and instructions)

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...

I figured it out - don’t go through the settings menu to nav - you have to have the map on the screen :/

did it fix the issue? Having same problem on JGC 2023 summitt

If you had this problem on delivery, you should have taken it to the service department, it’s a warranty item and documentation is key to maximize your Song Magnussen rights. Every single thing needs to be handled by the dealer till the warranty is up.

Interesting.. probably should have .. but wasting a day driving to the closest dealer .. sometimes you have to weigh the cost of your time.

I hope you don’t regret get that first issue documented.. fingers crossed

True... however a data update would not really fall into the category of product defect but would reflect more on the competence of the dealer to adequately prepare a vehicle for delivery, as this update was available before the vehicle was released.

However, I am crossing my fingers akin to the person falling off the 42 floor as they pass the 12th floor ..."so far so good..."

Ditto for me as well. I inserted the USB, turned on the vehicle and was asked if I want to install the new maps. Vehicle did the rest and it appears to have fixed the reboots.

I agree I have a 2023 Wagoneer. This keeps happening. I also have 2023 Ram and this doesn't happen in it.

You need to search this site and follow the steps this is a documented solution (pretty easy for most)

I just updated my two Grand Wagoneers 2023s. The one GW kept rebooting the Nav saying something like "Tom Tom map updating" and would end Navigation or music. I used the Stelantis website to find the maps for the UConnect 5 here: Stellantis | Home (navshop.com)

It is 16.7 GB today. You first download it to your PC. It was 8 files. It took 50 minutes. I then copied all 8 files and drug them to copy into my large USB storage device that I first formatted for NTFS.
Formatting to NTFS is also required for backing up games and captures on external storage devices connected to Windows PCs.
Important Back up or transfer any files on your flash drive before starting this procedure. The contents of the flash drive will be deleted during the reformat process.

1. Plug the USB drive or external storage device into your Windows 10/11 PC.
2. Open File Explorer.
3. Right-click your USB drive or external storage device.
4. From the pop-up menu, select Format.
5. In the File system dropdown menu, select NTFS.
6. Select Start to begin formatting.

This transfer did not take very long.

I started the Grand Wagoneer and chose Navigation and plugged the USB into the port under center screen (USB C or A) and it recognized the devices and guided me to upload new maps to replace old ones. It took 30 minutes. Keep car running and do no unplug USB until complete. This fixed the rebooting issue and replaced old version maps from 2/2022 in my GW that were made in June and July of 2023.

Drove Standard length Grand Wagoneer today and no more rebooting the Tom Tom trying to update every 6 minutes or so. Now has 10/2023 map. this is worth learning to do for all Uconnect/ TomTom owners.

My husband and bought a GW 23 nine months ago. It has been at the dealership shop 12 times over eight months for repeated dead battery, two power steering failures while driving, entire dash going black twice, unlocking door failure with fob in hand, and that doesn't include the four recalls, six updates.... and it has now been in the dealership 38 days over nine months. We documented everything and kept all service receipts, which we sent to both the dealership and Stelantis , as well as, a Lemon Lawyer to see if they thought we had a case, which they said we certainly did. We did not go that route , though we let the dealer know that we had. We were never contentious, but made the dealer aware of the toll it took on us emotionally, financially, etc.
Be persistant, make your case continually to dealer and corporate. Remember, it's not the dealer's fault. It's the manufacturers fault for releasing this vehicle before fully tested. None of us are alone.
Know you states Lemon Law backwards and forwards.
We are now being offered a buyback from Stelantis. It's worth the effort.
We are now getting a buyback
Within a month we have been offered a buyback by Fiat Chrysler
