I am looking to tap off of the video signal that goes to the headrest monitor(s) so I can input it into my NavTV connection. This will allow the video from the rear seat DVD player to display on the front dash monitor. I know there is a video/audio cable with a connector that can be accessed when the back panel on the front seat is removed. Can the video (only need video) be split at that point and run to another input? Any advice would be greatly appreciated!
