How does one find out what the latest firmware is for uc4 since it’ll never be shown on the website?

Sometimes the TSB's are available online (Usually without the update files present), or people get a copy of the TSB from a dealer and upload it to forums. You might be able to call Uconnect and inquire as well. The last 3 that people have difficulty obtaining are the 34.2, 39.9, and 40.1... You'd think that Uconnect would let them be downloadable on their website, but it seems like if you're needing to do more than 1 update, they really want you to go to a dealership to have them installed (which is unfortunate, because there's going to be a labor fee and each update can take 30-45 minutes).

Hello.
I have the exact same SW version and really would like to get that update file, please?
I also have an issue with that radio frequency. I imported my 2020 Ram 1500 limited from Canada to Estonia but can not get these even number radio stations tuned. Maybe these updates will help?
I upgraded to 40.1 by buying the 2 usb sticks (one was firmware & one was nav) from www.navigation.com Wasn't cheap - about $150 if I recall correctly.

Send me a DM with the VIN so I can take a closer look. As for the radio frequencies, that's typically a radio module. You will need to change it out to a European radio module, and you might need to modify the blue fakra on the radio (cutting the flanges off, but not the locking tab) so the curry antenna plugs to it for GPS. Or you can get a fakra converter cable like this one. You might be able to find one on eBay, teal is what you're looking for, for neutral connection keys.

I have a 21' Limited Ecodiesel with these stats:
Software version 22.12.10
Application Version USA-SBX-12.1-PR39.92.0-20220324-PSFRM
I was able to download the 40.1 update files from the link in post 47, put the files on a USB and boot in my truck.
Upon inserting the USB I get two screens presented on the console.
First screen (which is hidden by the second screen presented) gives the message "Cannot Update Software. Software not compatible with vehicle."
Second screen gives the "New software and features are ready for your Uconnect system. ....." with the Update Now and Decline choices both available.
I closed out the second screen so I could read the first screen. Based on the verbiage in the first screen I closed it as well and did not proceed.
I would certainly welcome any input you might have on whether or not I have the correct update.
Thanks for your ongoing contributions and support!

Make sure when you put the files on the USB drive you did it the way the instructions told you to.

Don't think a software update will fix that

Do you tink it can be the module?
Thank you for taking time to respond to my post. I originally put the files in the root folder of the USB. This appears to be what caused the error message in the first screen. When I copied the folder "VP4R_Update" into the root folder of the USB and left all the actual files in that folder (i.e. F:\VP4R_Update\) the initial error message screen ceased, and the update loaded successfully.
Thanks again for your time!
