This 3-piece car-dock works with HTC Handsets. With high quality rubber over-molds, and a dual, spring-loaded metal latch, the phone sits firmly in the Dock. The open design also ensures the volume and power buttons are accessible. Protective cases or extended batteries can be used with the xProDock thanks to the spring-loaded latch and extendable feet. A micro-USB cable for charging is included. The ROK II suction Mount features a disc with an adhesive bottom, making it possible to attach directly to any windshield or hard surface on the dashboard. For soft dashboard surfaces, a separate disc is included. The ROK II provides a virtually vibration free driving experience, ideal when capturing HD video while driving. The 17 mm industry standard ball joint used with the mount makes it compatible with alternative mounting solutions like ProClip, KUDA, pedestal bases and AMPS plate, etc.
