Hello, my name is***** to Justanswer! Give me just a few minutes to look up some specifics, I'm working on this now.
It is possible that the wiring on the back of the radio has gotten compromised. This can happen with a foot, a rodent, or just vibrations over time. Check to make sure the antenna is plugged in firmly on the back of the radio. The same goes for the backup camera. Loose connections will cause what you're experiencing, and since you have two separate symptoms that occur to damage to the same spot, that is where to start.
