This handy window-mount unit has a suction-cup base with a locking clip and includes a mount clip that is compatible with the DriveTrack 70. It features a bendable, flexible arm that is just under 9 inches, so you can adjust your Garmin to the perfect position while hunting from your truck or while driving. The ball-mount tip fits many Garmin products and the included MountClip is compatible with the DriveTrack. Just pop the MountClip onto the back of your DriveTrack for a safe and secure mount. As an added feature, this Window Mount also accommodates the Astro 320, Astro 430, and Alpha 100 with the purchase of an optional MountClip-HH (sold separately). This additional MountClip allows you to easily switch between your tracking system handheld (Astro or Alpha) and your DriveTrack. Made from sturdy, heavy-duty materials that are built to hold up to your roughest hunting conditions.
