I too have an 07 Avalanche with the Nav, but I have the rear DVD also. Does this mean that my Av is prewired for the camera? If so, then I would need to install the cam and have the dealer turn it on?
Thanks for the help!
your one is half way prewired. no need to take radio out.
You can find those camera wires at passenger side kick panel.
so all you have to do is install camera, run wires to passenger kick panel, and reprogramm radio
