Thanks for the info. If I wired the relay "trigger"(86) to the 6v 16pin on the HU would that work then? According to David:
1) You turn on ignition key (to ACC or ON), and HU receives +12V Accessory power
2) HU activates its +6V camera power lead
3) HU looks for a video signal from the camera
4) If the HU does not see the camera video within 5 seconds, it shuts off the 6V power and leaves the rear camera feature disabled.
5) If the HU does see a camera, it enables the rear camera feature. The HU shuts off the +6V supply after 60 seconds. Whenever you shift into reverse, the HU activates the +6V supply and displays the camera image. When you shift out of reverse, it reverts to the audio or navigation display, but leaves the camera powered for 60 seconds more.
So it will activate the 6V camera lead, power on the 12V camera through the 12V ACC line, "see" the camera and leave the 6+ line active for 60s and keeping the camera active and after 60s it will disable the camera. Just need a 6V relay now, or a way to boost the 6V signal from the HU to 12V.
