Rear View Camera:
I spent the better part of this morning hooking up the rear view camera. It was extremely easy to hide the camera cable along side of cabin under the various plastic covers. You don't even have to remove anything on the side. I drilled a hole in the middle of the bumper using the camera's drill and hooked up the +ve and –ve wires to the reverse light.
Edit:*I am now able to automatically activate the rear view camera when reversing.
The easiest way to automatically activate the rear view camera is to go out and buy a long wire and run it when you run the rear view camera RCA line from the head unit to the back of the GV.
Connect the newly purchased long wire to the pink wire coming out of the Head Unit (look at the diagram in the manual, it's called the “backdraft radar testing line”).
Run it to the back reverse light and connect it to the +ve wire of your reversed light. This way, the head unit will be triggered by the reverse signal.
So to recap:
connect yellow RCA cable to the CAM slot on the Head Unit
connect wire to the pink "backdraft radar testing line"
run both the wire and the RCA cable to the back of the GV
Now connect both your long wire and the red wire from the camera to the red wire (+ve) of the reverse light and connect the black wire from the camera to the black wire (-ve) of the reverse light.
