Does anyone have any experience/advice for rearview cameras? I have a 2008 Dodge Caravan purchased new. The rearview camera has gone out, it senses when the car is placed in reverse but after the "Check All Surroundings" message displays a black screen. Had it checked by the dealer, was advised everything was fine between the camera and the unit, so the problem is internal to head unit. Quote new was over $1600 installed, the tech suggested I get a used/salvage unit, which I did. And the replacement until does exactly the same as the original. Everything works great except the camera. So the replacement has the same failure OR the original diagnosis was wrong. I hate throwing a lot of money into this but if there is a reliable solution short of giving the dealer a ton of money I'd like to fix it. Thanks!
