Nokia CK-20W Bluetooth Carkit with A2DP capability

What have been your experience with it? It seems to be too new to have feedback on the net yet because I have not found much. Is there any option besides the CK-20W? I like the fact that the music goes to Line In at the radio. The Parrot equivalent (MK6000) totally hijacks the car speakers therefore any EQ or sound processing is lost. Thanks"
