TomTom Map Updates for Uconnect 5

do you know how to avoid getting the error we keep getting? Upon plugging in the USB stick, it says something like map files have been altered/changed. Please re-download them & try again.

I don't know what to tell you, I haven't had any issues downloading the map updates.

I got that message as well. I had to reformat my USB drive, using a PC, then transfer the files to the drive. Also, make sure you format the drive correctly. I think it has to be MSFAT32.

I think ours is already formatted to FAT32 but I'll double check.
 
Any USB stick over 32gb cannot be formatted to fat32. You need to use guiformat.exe if your USB stick is bigger. At least that's what I found.

 
v2026.09 is available.
