You should read my post just above. Putting one of these in your car is just plain retarded.
It's pretty well-known that audio over Bluetooth is pretty poor. Bluetooth just can't transmit audio at high quality. In the home it may be convenient for some low-level listening... but in a car, and for anyone that wants their music to be clear -- Bluetooth is just for morons.
Well color me a retarded moron. In for one. Hope thats okay with you, since you seem to really care about what people do with their own money.
