I stupidly used turtle wax ice on the interior of my car on the first day of ownership... everything was good until I got a bit of the stuff on the NAV screen. I tried to wipe it off and smeared more crap on the screen... I lost my mind and didn't stop trying to fix the mess until the bloody screen was a bloody streaked mess.
My wife saved the day and suggested I wipe the screen with a microfiber shammy... the type you use on your eye glasses. Fixed. Long story short... don't get any crap on your NAV screen.
