The simple, classy way to mount your GPS! Works with ANY GPS that accommodates the standard 17mm ball.The faceted lug on the stem gives you six mounting options to choose from. The 17mm ball (same size ball as a car mount) utilizes your stock GPS cradle or the socket-mounting hole on the back of your unit and rotates/tilts just as it does in your car! Just snap the cradle or unit directly into the ball mount.Note: your GPS must accept the 17mm size to use this kit; often that means an extra piece that came in your GPS kit (or that can be purchased separately) that "clips" onto the GPS. Fitment includes many Garmin Nuvi, Magellan Roadmate series, and TomTom GPS. This kit mounts on any round bar (1" to 1-1/4" diameters). See the Fitment Tab for sizing details. Kit includes Mounting stem with 17mm ball (stainless steel); Mounting bracket with UltraSecurity feature (chrome); and all necessary hardware.
