I just replaced my battery, and now the radio wont work. I realize the sound system goes into a safe mode, but no lights work on the radio whatsoever and "safe" is not displayed on the sceen and the fuse is fine. All of the other lights, buttons, and functions work but the radio will not respond to anything, any help?

 

have you got any documents on the radio code? a 4 digit code? if not its a dealer job

 

Yeah I have the code, but I can't enter it since nothing lights up.

 

then it could be a blown fuse on the rear of the radio 10 amp I think
