Anyone know if there is some type of video input into the NAV system. I have the system with the 5 camera system and also had a TV/MY VIDEO button that seems to do nothing. I wonder if there is some way to have a video input go into that TV button input. If so my plan is to wire in a little Chromebox into that video input to use as google maps navigation, plus have full use of pretty much any app through the video screen. Audio I really don’t care about. Been looking through all the NAV threads and looks like maybe it is possible but nothing really stands out.
