The GN079WD-SBH-AMPS sticky suction mounting pedestal can be used as a replacement, upgrade, or as an addition to an existing pedestal. It is compatible with devices having a 4-Hole AMPS pattern, including vehicle-specific mounts (VSMs), cameras, GPS devices, audio/video receivers, or satellite radios, including Sirius S50, Sirius XM Onyx Plus, XM Onyx EZ, Sirius XM Lynx, Stratus 7, Dock & Play, and Sirius Dock & Play (sold separately). This mounting pedestal is also ideal for mobile radio holders, housings, and other devices used by public safety, construction, and utility applications. The 4-Hole AMPS pattern consists of four holes located in a rectangular pattern spaced at 30.17mm by 38.05mm (measured as the center-to-center distance between holes). This package includes only the Sticky Suction Mounting Pedestal featuring a 4-Hole AMPS Head and 3" Articulating Arm, and an optional 3M adhesive dash mounting disk. (Devices sold separately.) The Sticky Suction Mounting Pedestal is ideal for car dashboards, windshields, and other flat or slightly textured surfaces. The mount's base uses a powerful combination of polyurethane gel and suction to provide a maximum surface bond. The 3" articulating arm of the pedestal adjusts vertically and provides 360-degree rotation, giving you the ultimate flexibility in viewing the device from any angle. To install, simply clean the mounting area with the included alcohol pad to ensure an optimum grip, then set the pedestal and push down on the one-touch lever to engage the suction. In order to prevent permanent indentation marks on dash surfaces made of soft vinyl, leather, or similar materials, Arkon recommends using the included 3M adhesive mounting disk. While powerfully strong, the sticky suction mount is also easily removable and reusable. If the mount loses performance due to dust and dirt on the sticky suction pad, just rinse the pad with a mild liquid soap and warm water, then let air dry to restore the suction.
