Radio head not activating camera screen when shift in reverse

[Tahoe_Denali]

07 Denali - The radio does not go to camera screen when shift into reverse. I have confirmation that backup lights are working. Recommendations appreciated!

Maybe someone will come along who has experienced this in the past. One really needs a Tech-2 or equivalent to work on these things. Welcome to the forum by the way. Do you also have a Tahoe?

you really need a tech2 to diagnose but without that I would check the wiring harness that goes from the body into the rear hatch, see if any of the wires are broken or chaffed, it is top dead center when you open the rear hatch covered with a rubber boot, sometimes that boot comes loose and the wires get all messed up or it just gets all worn out.
