I did the same thing to protect the display. I just used clear wide packing tape. When it get scratched I peel it off and put another piece on.insti08 said:I only have one issue with mine, the display scuffs easy. So I cut a piece of screen protector from a sheet for my Nav and put it on the display screen. I also put a coat of plastic wax on it before I applied the screen protector. Other than that it work great!
