Mysterious Issue: The backup camera not engaging properly when truck put into reverse. It does not go on until you take take the vehicle OUT of reverse and go back into park. Also, when you start the vehicle in park, the camera is on.
I connected the reverse sensing wire from the AVIC-Z1 harness into a wire that went + when the car was put into reverse. It was the same color code as the wires at the tail light reverse bulb. I tapped from the wire coming out the back of the Reverseing lamps relay behind the central junction box (AKA - drivers side dash fuse box). Prior to tapping, I tested the wire for proper operation and it indeed went + when the vehicle was shifted into reverse.
I'de be very grateful for your help on this. I'll be opening the dash again in the next day or 2 to install the new steering wheel interface so I could do more tracing (fixing hopefully) then.
