Has anyone experienced a scrambled video from there reverse camera. I have an aftermarket kenwood deck and the factory reverse camera mirror. They always functioned fine for years then all of a sudden now everytime I put her in reverse I can barely see. It gets all scrambled and looks like when I tried to watch playboy on my parents TV back in the day by putting the cable box channel selector between two channels... How do I know if my camera is bad or if its a loose connection or wiring issue?
