I've had my truck 3 years (22 3500)and the radio presets still occasionally reset. It is the 8.4 non nav model radio. The last time they reset the uconnect disclaimer screen showed when I turned on the truck but I can't say if it has any connection to the presets resetting. I've had it to the dealer multiple times and they have not been able to reproduce the presets resetting. The uconnect version is 141. Does anyone have a solution to this yet?
