Use with the automotive mounting bracket that comes with most Garmin GPS units. This mount has a neoprene type base that hold the unit in place on a dash with ease. You can even do steep turns with this and the GPS does not move. If you do not like the yoke mount or if you are in and out of several aircraft with your GPS this is a nice alternative to the GPS bouncing around the cockpit. This unit will not work with the III Pilot.
