Did I read correctly that the BT in the iPhone only works with a "headset" (and not a car)? Does that mean I cannot use the iPhone with the built-in-vehicle BT? I have a 2006 Land Rover LR3 that previously connected with my Palm Treo650 and is currently working with my wife's Motorola Razr. Here is the Land Rover BT compatibility listing from landroverusa.com. Unfortunately, is NOT on this list. .
