My new motorhome has nice big 10" screen infotainment system and I would love to put my towball camera feed to this screen , does anybody know if this is possible and which plug would I use . I have managed to remove the screen to reveal the head unit behind with several spare plugs and fakra connections but I have no clue if any are for a camera feed . Just wanted to ask before I put a 4.3" screen on the dash board .
