When I start my engine and play a dvd my ceiling flip down video start to show lines and distortion. I currently have the 12v, acc, and ground all hooked up to my headunit. I tried both video out 1 and 2 on my headunit and it does the same. It only does this when I start my car. My main headunit double din tv is fine its just the flip down monitor thats doing this. Can someone please help me and let me know what I have to do to stop this problem. Thanks.
