I purchased the Naztech n4000 car mount/dock. I don't know how to get the Thunderbolt to recognize that it is in the car dock. Has anyone purchased a car dock that enables the car dock applications within the Thunderbolt to work? I downloaded the Car Dock app from the app store, and nothing works. If anyone is thinking about the n4000, I'd rethink it. The gooseneck's total length is 6in. This places the phone down near your knees if your cigarette lighter is on the lower portion of your dashboard. Talk about talking your eyes off the road. The mount holds the phone extremely well, but the gooseneck doesn't work for me. Does anyone know why the TB does not come pre-loaded with a car dock app like the Droid?
