I'm looking for a car dock to go with my iPhone 4 and JVC iPhone compatible radio. I found this: http://www.dension.com/iPhone-car-accessory/car-dock-for-iPhone (the dashboard mounted dock, not the window mount) I need a dock that I can attach to my dashboard, and has the 30-pin connector always attached. Kind of like the Magellan and TomTom docks, but I'd prefer not to use a windshield mount. The above link is $130, pretty steep for just a dock. At least the TomTom and Magellan docks do more. Anyone know of a similar dock as the Dension one that's under $75?
