I have Avic D1 and would like to install a backup camera. Does anyone have a picture of the wiring connector that is on the back of the unit? Are all the cameras universal so I can pick up just about anything or so I have to pick on with the right connector?

all you need is a back up camera that has a RCA;s video out plug (which most do) then you will also need to run acc power and ground to the camera, and make sure that the reverse wire from the avic is hooked up to the right wire in the car(that way the avic knows when to switch to the camera video source) and you are all set.
