i just installed a refurb avic x930bt in my subaru forester with a rear view camera. the camera is hooked up to the reverse light for power and i believe tapped in correctly to the reverse signal wire. the camera comes on when i put the car in reverse and after a few seconds the camera image flashes and a warning is superimposed that says the image may be reversed or something like that. now when i take the car out of reverse the camera stops displaying and the screen goes black except the warning is still on the black screen. i have to hit the mode button to switch back to my audio settin
