I have an Xtrons stereo head unit. I have attached a reversing camera that switches the camera image to the head unit automatically when I put the vehicle into reverse and switches back again when I release from reverse.
If the external lights are not on, there is a buzzing noise when I put the car into reverse. If the external lights are on, there is no buzzing noise!
The camera's picture is perfect whether the lights are on or not.
I have checked all connections including the
earth which is connected to the body of the vehicle is good.
Any ideas on how I can get rid of the noise?
