This is the RAM Handlebar Mount kit for the new Garmin eTrex C models. These are the new Color eTrex models, not the original grayscale screens. The kit includes the cradle, the diamond base, a medium arm and the U-bolt handlebar mount. This kit will mount to handlebars up to 1" in diameter. Larger U-bolts are available for different handlebar diameters.
This allows you to power your eTrex Color model GPS from the cigarette lighter in your car. It will work on your bike, but these units are definitely not waterproof.
