I haven't had any luck either using PhoneControl or Mobilephone.net or any of the other software based solutions to connect a cell phone to your computer over bluetooth for hands free calling. There are either problems with the software, the bluetooth stack, the dongle or the front end

There seems to be quite a few devices out there that offer this functionality and it would seem to me that someone could have already hacked the hardware to interface with a carputer.

Any projects out there like that?
