BMW 745 Forum : “Hands free blue tooth”

Hands free blue tooth

I have a Samsung BlackJack phone and want to hook it up to the factory installed phone system in the iDrive and be able
to use the installed keypad on the dash.  Has anyone done this?  There is an adapter piece that I found on the internet
that slips into the cradle in the arm rest storage but this does not power my phone.  Has anyone purchased this
adaptor?  Does it sync up with the iDrive and on board phone system and built in hands free?  Please respond.  Thanks.
