If you have 6fl (iPod / iPhone) adapter you can play through the radio and view on the Nav screen. If you have 6nf (SmartPhone) then by definition you MUST have 6fl. With these 2 options (and premium package) you can get a phone specific cradle to mount in the car. If you use the cradle (snap in) then your phoner connects bluetooth but the signal goes through the side mount antenna and it charges. You also get your music thtough the rasdio and the music library etc. on the Nav screen (using the 6fl connection).
You need ALL4 - Premium, 6fl, 6nf AND the correct cradle for this to work. ONLY THE CRADLE CAN BE INSTALLED BY THE DEALER FOR THE E89 SERIES. My dealer learned the hard way as he is reimbursing me $700 as they THOUGHT that they installed the Smartphone adapter AND the cradle at the dealership. WRONG !!!!
If you have a 3GS phone and 6fl option you must get the new Y cable adapter available in December '09 (part number (61 12 0 440 812) . Part number 61 12 0 440 796 will NOT charge the phone due to Apple changing from firewire to USB power connections. The new cable DOES CHARGE the phone BUT it does NOT eliminate the incompatibility message that appears on the phone screen. I understand that they are working on this though.
