Welcome to the forum. You have the Uconnect 5.0 or Uconnect 8.4 radio?
The radio power fuse is F80, but you may be better served if you disconnect, pause & reconnect the neg (-) battery terminal.
Does the radio ever have times when it does get past the start-up screen & works, or is it locked on the start-up screen?
Uconnect 5.0:
Uconnect 8.4:
Anything plugged into the underdash diagnostic connector or any accessories added to the electrical system that might be causing interference?
