All of a sudden today, my rearview camera has stopped working. When I put it into reverse, the display screen doesn't change - it just stays on whatever screen is up on Carplay (Google Maps, Pandora, etc). When I tried pushing the camera button, nothing happens. The light doesn't even come on when I push it. Any thoughts as to what the problem could be? Is it something that I could fix myself? I have 1000 miles left on the warranty.
