Arkon's GN032-SBH-AMPS handlebar mount can be used as a replacement, upgrade, or as an addition to a current mount. 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. Formerly an industry standard, 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 mount package includes only Arkon's Bicycle or Motorcycle Handlebar Mount featuring a 4-Hole AMPS Head (holders sold separately). The bike or motorcycle mount fits on handlebars measuring up to 33mm in diameter and is easy to install with a Phillips screwdriver. The mount's swivel ball adapter head rotates 360°, providing the ultimate flexibility in positioning the smartphone or GPS at any angle.
