The Garmin® GPSMAP Windshield Mount is a marine-grade aluminum mount with a locking suction base and custom plastic cradle. The mount is designed with a one-inch diameter patented rubber ball-and-socket system that has adjustment points at the cradle and base. With a twist of the arm knob, you can move your Garmin GPSMAP 60, 60CS, or 60CSx to its optimal viewing position.
