I have a Motorola Roadster in the car I use mainly for work with the same functionality. Unless your in the middle of nowhere, trying to stream audio through the bluetooth/fm transmitter in your car, is pretty much useless. There are so many stations in the Pittsburgh area and interference that it never works correctly. If yours works for you perfect, but hard wired in the form of a cable or dock is always going to sound 10x better. I have not tried it in a home application.
