So I bought a 2011 Equinox and when I would shift into reverse the camera would come on in the mirror but was vertical lines in the picture. So it just stopped working before I could trouble shoot it. So I replaced the camera and the mirror but it didn’t fix the problem all fuses are good! When I put it in reverse the green light just blinks off and on no picture. Do I need the radio replaced? Or what is the fix for this please help. Going to give it to my son so I want to fix this first!!
