How to get radio update files

Does anyone have a link to the RAM files for an 8.4" screen? All I'm seeing here is 12" files. I went through Uconnect by entering my VIN and it says I'm up to date when I know I am not, I'm 22.66, not 40.1.
 
Using the great informations in this tread, I successfully updated my 2019 from LR-34.31 to 39.7 and then to 40.1. Took a couple of tries to find an USB that the truck liked, it ended up being an older 4 gig USB. For some reason, I could not get 39.9 to load from 34.31 but 39.7 worked and then to 40.1

It was nice to avoid paying the dealership to do these updates.

Did you format the USBs to the correct file system (FAT32) per the TSB procedure?
 
Does anyone have a link to the update files? The provided google drive link that previously had all the files now says the folder is empty. Specifically needing 39.7

Has anyone here done the retrofit upgrade from UC4 to UC5 on their 12”?
 
Ok just found this thread
My 2019 Limited recently been giving me issues with CarPlay and doesn’t like when my iPhone has a full battery and will constantly cycle connected to not connected.

My current version is 20.10. The TSB says below 20.16 not recommenced. Am I ok to update it step by step with the next version up and then up after that?

My guess is I would need to go to 20.16, and so on so so forth and do multiple updates to slowly get up to 40 correct?

The pushing the bottom left and right for 10 seconds to get the version information DOES NOT
work on a 2023 UC5.
 
Just tried going from 20.10 to 20.16 and got the message that radio not compatible with upgrade file

I have a 12uax and am at software 28. For the last week the radio will turn off every 4 - 5 mins. GPS is not even close and clock is way off as well. gps has no connectivity for location services. I tried to update to 34 with the usb it gets to 19 % then the radio turns off then on again and starts over. I can never get passed the 19%. anyone have any ideas what to do?

If you are ar KR28 you have pre-recall software. When it stops what error does it give? Each number corresponds to a different issue.
