Arkon's GPSWPCS532 handlebar mount is compatible with all GPS devices with 5" screen size from companies such as Garmin, TomTom, and Magellan. This mount includes Arkon's Bicycle or Motorcycle Handlebar Mount with Water-Resistant Holder. The water-resistant case zips open for easy access to the device and features a touch-compatible plastic face that allows you to operate the GPS while in the holder. This case does not provide easy access to phone chargers. Sturdy removable foam pads are included to ensure a snug fit for your device. The bicycle or motorcycle mount fits on handlebars measuring up to 33mm in diameter and is easy to install with a Phillips screwdriver. (Three handlebar spacer/adapter rings of different widths are included with the mount. Choose the appropriate size for optimum mounting to your handlebar.) The mount's swivel ball adapter head rotates 360°, providing the ultimate flexibility in viewing the GPS from any angle.
