I just installed my Dietz 1217 and ME3. Everything seemed to be working fine until I went on a long drive yesterday. With out any ryme or reason the video cuts to a screen saying "Note: TV is not insalled" or something to that extent. The audio keeps going but not the video. It will flash it for a few seconds, then go back to the video, then a few seconds later back the the warning, ... it does this 3 to 4 times then will quit for 6-10 mins, then repeat... its quite annoying. Any suggestions?
