Got the document thanks, however this does not have the correct instructions for my 2005 530d.
It speaks of a button/switch on the centre console that needs to be pressed, mine does not have this button and I've looked everywhere properly.
Mine does have the bluetooth/phone buttons on the steering wheel though so it should be able to pair.
On the iDrive menu under "Communication" there is no "Bluetooth" option, all that is displayed under the phone section is "Contact your dealer", any ideas?
PS. When I contact the dealer they say to bring it in and of course there will be a charge...
