I got a license mounted Koolertron CMOS camera off amazon for like 12 bucks. Ran the cables to all the right places. Yellow up to my head unit, a pioneer AVH-P2300DVD, and into the Rear View Camera Port. The power and ground were tapped into my driver's side taillight. Green Pos. White with Black line Ground.
Aaaaaaaand, it doesn't work.
I tired hooking up the violet/white cable from my head unit to a wire that only got current when in reverse. When I would hit the rear view icon on the screen, it just displayed a black screen with a message, "Image may appear reversed" but no signal.
I was frustrated, so I plugged it into the Video In port and switched to AV. Nothing. I am out of ideas. The head unit has a video relay bypass that I installed on it, and I know that the thing will play DVDs and other video, so the only thing I can thing is I got a lemon camera? I mean it was only 12 bucks.
Any other ideas for me guys?
