Arkon offers two different Multi-Angle Pedestals. This model, the CM48, adjusts to fit all angles and can even allow you to view a phone or PDA horizontally. To install, use either the strong 3M adhesive for regular installation or screws for a more permanent installation. The base of this pedestal is shaped like a triangle and is flat. You therefore will need to mount it to a flat surface only. Note: Only mount with screws if you desire a permanent installation. NOTE: This pedestal includes all the necessary adapters to work with ALL of the ARKON cradles including the new Powered PDA Mount solutions. It also works with the SKYFi and Roady receiver.
