Uconnect T25.51 Update

[Roman2179]

Installed T27.46, all seems to be working still. Outside of a couple minor UI changes, nothing really new. No full screen android auto.

Nothing broke though so I will call that a win.

You just haven't looked hard enough yet

I only messed with it for 10 minutes but nothing obvious is broken. Whether that holds up or not is still to be determined. Either way, it's major step up from the disastrous T25.48 update.

Haven't found any issues yet. Only been a few drive cycles including pulling the camper 20 miles.

Anybody with a 2023 Ram see this yet?

Change log for T27.46?

 

[Njh3409]

Link removed. It would appear some people were having issues with it. I personally update 2 radios from T25.48 without issue. Radio was from a MY22 TRX. No issues with gps or SiriusXM.

Here is a link to the T27.46 USB update. I have installed it and after 3 days use it is pretty stable.

Is there a specific site to look up the change log? Or is there somewhere on this forum where it’s usually posted?

This release was for a camera not displaying at times recall if I am not mistaken. When I installed the change log was blank on screen.

So can upgrade be done from S26.17 to T27.46 on MY2022 directly?

I tried to install it and this came up. Currently, I don't have satellite radio or GPS.

I got the same error.

I pulled the link. I had zero issues with 2 radios. One was a stock 22 trx and the other was a retrofit in a 19. Both started out with MY23 T25.48 and both have working GPS and SiriusXM before and after.

I used your file to update my Rebel and a friends Limited. Both MY23, both were on 25.48, and both have NAV and SiriusXM. No issues. Thanks for posting it!

NOTE: On my first attempt, I accidently turned the key from AUX to RUN while it was at 20% and immediately got an error. Put your truck on AUX and leave it alone until it finishes. Not sure what the error was. I restarted the update and everything went fine.

I re-uploaded the T27.46 USB update because I keep getting request on my google drive for permission to the file. Freshly uploaded from the USB drive I used to installed both radios. I already had T25.48 installed. Hopefully someone has had success like me. Use at your own risk all update are as follows oldest to newest. S25.15, S25.17, T25.48 and the latest T27.46. I have personally used all version in the order they were released on 2 personal UC5 MY22 and a friend with a MY23 version T25.48 to T27.46. Again use at your own risk. If you have a truck that was originally equipped with the 12" UC5 your should get the normal over the air update eventually.

Based on other users and myself I recommend updating to T25.48 first before installing T27.48.

Glad to hear I was starting to think the file got corrupted somehow. Not trying to brick radios or anything.

Do you mean you lost those features, or you didn't have active subscriptions?

If the latter, you actually do have satellite radio (you just can't listen to programs without a subscription) and GPS is a passive system that receives at all times - Navigation will still work using GPS location, even without an active subscription for NAV traffic updates. Having said that, it might be a different checksum pushed to trucks without those subscriptions compared to the posted file. As mentioned, it should get pushed over the cellular network to your truck eventually.

I have this Build Number: FCA-MY23.T25.47-PROD and I currently do not have GPS or SXM. I wanted to update to this newer one but at the end I get that message that I showed in the photo that I showed here

It was where they turn on the accessories, not in run
