I have a Sony bluetooth car stereo and was playing with BT last week. It's kind of quirky, there's inputs for both BT phone AND BT audio. When mine's all paired up, and input set to BT Phone, I can push the "Phone" button on the remote and it will accept voice command. I think there's a button on radio head for same.

Also works when Sony input on BT audio and phone rings, can answer with phone button. I don't beleive can initiate phone call without switching input to BT Phone.

Worked similar before with Motorola/VZW W755.
