Arkon"s SM429-SBH smartphone mount bundle attaches to your car"s horizontal air vent louvers. Your car"s air vent is a popular mount location commonly used with devices featuring GPS applications as it positions them up high in the vehicle. The air vent is the preferred method of mounting in Minnesota and California where the use of windshield mounts are restricted. The compact design features Arkon"s easy to install vent clips made of strong polycarbonate blend of plastic. An adjustable swivel ball connection provides full 360 degree positioning for optimal viewing. Arkon"s Mega Grip holder is not phone specific, though it works with nearly all phones including those that have protective cases or skins on them. The Mega Grip holder utilizes patented side grip technology with a quick push-button release mechanism that activates the Mega Grip. Squeeze the cushioned Mega Grip arms to secure your phone in the holder. Recommended for ALL versions of the iPhone including the new iPhone 4, Samsung Galax S phones, Motorola Droid, Superphones like the EVO 4G, HTC HD2, HTC Desire Z, Droid X and devices like the BlackBerry.
