An alternative to windshield and dash mounts, the AirVentMount won't block your view of the road. It provides more options to view your handheld while conveniently keeping it within arm's reach. It's also great for allowing passengers access to the GPS easily and comfortably. This mount fits most car, SUV, truck, and other vehicle ac vents and is auto-spring locked and had rubber-lined grips to provide a secure, steady hold. Easy to use - just pop the ball joint into a ball-mount bracket or cradle of your choice (various cradle options sold separately). Insert the AirVentMount grips onto your vehicle's air vent blade and tighten the nut. No tools required! Rubberized grip pads are fully adjustable and tighten to fit thin or thick air vent blades. Also works with horizontal or vertical air vents. Compatible with Garmin Astro or Alpha with the addition of various cradle options. We recommend the MountClip-HH or Klipzer (sold separately). Also compatible with many other Garmin products, including most Garmin navigation devices that accept the standard ball-mount insert.
