From what I understood the official car dock did not put the phone into car mode. Low and behold now that the Car Dock is on Verizon's store http://www.verizonwireless.com/b2c/store/accessory?action=accessoryDetails&archetypeId=12301 , the description says "This windshield mount and Holster combo positions your HTC DROID Incredible within easy reach. The unique design holds your device securely in place and allows it to into map mode automatically when placed in mount. Includes window mount and phone holster.". Interesting.
