Hi, I have installed an aftermarket head unit which is great, one issue I can’t resolve though is that whenever I put the car in reverse the unit switches to the (non-existent) rear camera. From what I’ve read the only way to stop this is to cut the cable in the wiring harness which sends power into the radio when you put the car in reverse.
Despite much looking no wiring diagram has helped me identify which wire is said one. Can anyone help me identify it please?
