The Nokia Bluetooth kit is essentially a hands-free kit for the car (now strongly recommended by current UK legislation), just without all the nasty wiring and cradle taking up space and looking ugly.

Once you set up a pairing with the unit (works with both my 8910i and my wife's 7620), all you need to do is get in the car with the phone in your pocket (or bag, or wherever you normally leave it), turn on the ignition and it sets up a Bluetooth link with the phone. If you get a call, it mutes the empeg and relays audio via a small speaker hidden in the footwell, and a microphone in the headliner. You have one button (the visible bit) to terminate calls/put people on hold/adjust volume etc., and it can also be used for voice dialling, which works very well.

Plus, there's no chance of you leaving your phone docked in the cradle when you leave the car!
