So the BMW one turns on for a few seconds when powered.
Thought of your problem if they powered the unit with reverse line instead of a line hot in accy.

Very interesting..
If I understand correctly, you would get the camera signal cutting in then out when the car ws in 1st gear.

The only thing is that I watched them work on the car and they could leave it in gear (assumed at the time it was reverse) and the screen would continue to fliker and on occasion would should the camera output for a second.
