Why not use it as a car mount for your HTC EVO 4G instead?
The Mountek MT5000 mount slips into the CD slot (or any other thin groove in the dashboard) and uses no suction cups, screws, clips, or adhesives. The adjustable cradle is attached to the mount via a ball hinge for easy viewing angle positioning. Installation requires no tools or windshield/dash space and can be done in seconds, as shown in the video below.
Mountek says that the MT5000 provides a firm, stable, and secure mount for most handheld devices, "even in off road or rough water conditions," and will not "bounce around" like other mounts.
The mount is available from a number of retailers for $19.95 each.[eBay | Amazon | Mountek]
