I gotta say Im stumped as well. I have the same equipment as Steven audiovox 200w and 920bt. They must not like each other. I can switch the rca feed from the camera to AV2 and can see whats going on in the rear, but I cant get the rearview to trigger on while having the camera plugged into the rearview input. I switch the camera polarity to gnd and it works when I throw it into reverse however its stuck in reverse camera mode...HELP!
