Anyone have a handsfree phone kit in bimmer?

ANyone have a handsfree phone kit installed in their Bimmer? How hard was it to install and does it properly mute the stereo? I am having one installed in my bimmer but I am concerned because the installer has never messed with a bimmer factory radio, apparently because so few have them replaced (to maintain the use of steering wheel controls). I hope this works instead of screwing up my radio.

Well it's back and it works. But it took him all friggin day to do the install and figure out which wires were which. The hookup is fine and the radio mutes with an incoming call or mutes when I hit the speakerphone on an outgoing call. I'm still haveing trouble getting the car kit to learn the voice activated dialing but other than that, it's good.
