thats the issue.... his screen does not support auto switching...... there has to be a way though.... How many A/V hook ups does you screen have? maybe you can use the ground wire on the reverse light and connect it to some kind of switch to make the screen change to A/V one.... that would of course involve moding the screens circuits.....
