Any other suggestions greatly appreciated. The video root menu still comes up on living room tv but can't control/play it due to warning screen on clarion unit. Remote for it and Jensen unit outside confirmed missing after thorough search so will have to replace. That part's easy.
OK..just to clarify. the disconnecting of the safety relay at the outlet allows the TV to be on while the engine is running. the issue you have with the video is at the Nav/Multimedia unit. there is a ground detection wire that is wired to the parking brake that needs to be connected to the chassis ground of the head unit. the easiest way to access that area is to remove the 6 screws that hold the plastic dash surround (with the radio, aux buttons, 12v outlet, and climate control unit) and slide it all out of place so you can see behind the head unit easily.
