I am having a problem with my backup camera that I installed. I connected it to my Magallen GSP as a monitor. When I put the Equinox in reverse the camera comes on but the picture is wavy and somewhat distorted. When I turn the key off in the garage the light go on and the backup lights go on for a few second and that turns on the camera and the pictures is perfect. So when the key is on I get a distorted picture. Can anyone help me with this problem?
