It's the Center Mount style and sells for $30 along with the Tilt/Swivel Holder with cigarette lighter charging cord for the Treo 650, selling for $70.

New car means I need a new mounting system. This is the best device holder I've ever used, holding the Treo exactly where I need it so I can see the screen at all times. Great for GPS navigation or just seeing who's calling. Completely secure and charges the Treo while it's in the holder. Price includes standard USPS shipping to any state in the continental U.S.
