his response:Any help is appreciated and I thank you for asking someone on the inside. If he doesn't know, maybe he can give you a run down of the backup camera system and how it works so I can troubleshoot from there. If it is all done in the camera then I need a new camera but I get a strong feeling that it's not. I have a 2013 Limited. Thanks for the help, again.

The camera module busses the signal to the BCM, then from there to the radio. It's an issue with one of those three components or the wiring"
