When mounted behind the windshield is the Zumo water proof enough such that I can be used in the rain?
Any Zumo unit is as waterproof as any similar Navigaor unit as the Navigator units are, in fact, Garmin zumo devices with a different look and few software differences. E.g., the Navigator IV is just a Zumo 660 with few cosmetic changes
