Designed for 9–32V systems and rated IP67, it resists water and fogging and fits into a standard 85mm dash cutout. The unit includes an external antenna for quicker satellite lock and provides Course Over Ground (COG), Speed Over Ground (SOG), trip, and adjustable odometer functions for versatile use on both land and sea.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly does the MAIMEIMI GPS speedometer get a satellite fix?\u003c\/h3\u003e\n\u003cp\u003eThe gauge usually acquires a GPS signal within about 30 seconds the first time; subsequent fixes are faster when the antenna has a clear sky view.
