The latest firmware is 24.13 and there is a user here named Jimmy07 who has posted it for download. I downloaded this to a USB and it installed without errors on my '22 Laramie GT. The link for download is on page 3 of this post: June Uconnect UpdateI'm in the same boat with a 22 TRX and the dealership was unable to get it updated. They are ordering a new radio and I'm not looking forward to that swap. I'm hoping someone will post a link so I can try to use a USB stick to update the system.
