I use a Parrot PMK 5800 and love it. It uses BT for both the audio and phone. No wiring at all as it plugs into your lighter socket. Transmits the audio via an FM transmitter with really good quality. Automatically pauses your music and puts an incoming call on your car's speakers when a call comes. Works as a very good hands free device for your phone. Controls your player to pause/play, restart, and play next track. Also has an input jack to input another device (eg. ipod) if you want. And best of all, unplug it from your car and put it in any other one with no additional setup. Mogul can be anywhere in the car or still in your pocket as there are no wires. Cost is just under $100 but for a combo BT handsfree and FM transmitter unit, it's reasonable.
