Looking for some technical help connecting a rear camera to my radio.
I have fitted the camera and run the cable from the boot to the radio and connected it all up. Supply (12v) is obtained via the reversing light. If I put the radio into test mode (power and search button and entered 92) and the car in reverse with ignition on I can see the image from the camera.
Without the radio in test mode, going into reverse radio does not show video but the parking sensors.
Is there something I need to connect to tell the radio to switch to video.
What did the two wires from the plug that I removed do as everything else is still working with them out.
