Are you referring to aftermarket or OEM tint. If you are in the US, most if not all states don't allow aftermarket tint on the front windshields except for the 3-4" band on the top. Most GPS units are suction cupped to the front windshield so this shouldn't be a problem. As for cleaning, almost any glass cleaner will work for OEM tint. You need a very mild, non abrasive cleaner for aftermarket.
