Fitted an aftermarket reverse camera(numberplate light one) and connected it to my aftermarket JVC stereo, with power coming from a connection to the reverse light.
When the car is in ignition and I put it in reverse, the camera is beautiful! No issues whatsoever.
However, once I switch the engine on, the screen flickers really badly and the camera screen itself seems to be moving below. My phone's camera is broken so I've found a youtube video which shows literally what my stereo shows when the engine is on and in reverse.
