I have just taken delivery of my 530xi and although my dealer told me that my SE K750i was not supported, I have managed to get it to pair with the car, after a firmware upgrade of the phone. I am able to view my contact list and dial from the car - this seems to have been an issue written up by many owners. However I am unable to get the sound to transfer to the handsfree system which is the whole point of this technology. When I first start the car it will work on the first call, but on a second call the sound will revert back to the phone which is so annoying. Does anyone have any suggestions?
