Maybe there is one but if so, I haven't seen it so far. Why does I look for such a Bluetooth car kit and why is is so interesting? Pretty easy - in this case you can use your mobile phone to playback your music files through your car HiFi system.
As you can read in my Samsung SGH-i300 review, the Samsung, as well as other modern mobile phones finally supports the A2DP Bluetooth stereo profile. The Advanced Audio Distribution Profile (A2DP) is designed to transfer a stereo audio stream like music from an MP3 player to a headset or car radio. It includes mandatory support for low complexity subband codec (SBC) and supports optionally: MPEG-1,2 Audio, MPEG-2,4 AAC and ATRAC (from Wikipedia).
As I've mentioned in the review, at the moment I'm suing the i300 together with a Motorola Bluetooth Stereo Headset while walking or biking while in the, car I'm using a Parrot Bluetooth car kit.
Now, if I imagine that such a car kit would also supports A2DP, I could continue listening the same music from my mobile phone while driving, in best case with a seamless handover from the stereo headset to the car kit and back.
Currently I'm using my 40 GB iPod with iTrip to send the music from my iPod to the car stereo but such a car kit could easily replace my iPod even if it has 13 times more storage capacity. A single source would be be too good.
Maybe there is such a car kit already and I'm not aware of it? If so, please let me know. What do you think about such a Bleutooth headset/car kit/mobile phone combination?
