I have a Pioneer head set and a Pioneer BTH 200 Bluetooth unit in my car. The Iphone paired and receives calls wirelessly perfect. When I first installed the Pioneer BT-200 my Iphone/iPod played thru my stereo just fine. The iPod application will has not played through my stereo ever since. The next time I drove my car, no Bluetooth IPod connection, just Bluetooth iphone. Can anyone help?
