So my wife just bought a used 2015 Cruze LT. When she brought it home I was surprised when she said it didn't have a backup camera as I figured it would being a newer car with a big touch screen. Well her plate came in and when I was putting it on, low and behold there is a backup camera back there...It just doesn't work for some reason. I've read where people have issues with a black screen but I don't even get that. The screen stays on whatever screen it was on before shifting to reverse, no beeps, no warnings, nothing. I don't know much about these cars but they wouldn't have the camera back there if it wasn't part of her package would they? Any help here?
