To get the smart phone integration working you need the following factory options:

644 - amongst other things, gives you the base plate in the centre console/armrest
6NF - enables music play from iPhone while it is docked in cradle
6FL - gives you USB slot in armrest, and iPod interface in iDrive

Then on top of these, you have to buy the right cradle (or USB snap-in adapter as BMW calls it) for your iPhone. In Australia, this accessory is not included with any of the options above, and must be purchased separately or worked into the car deal.

To find out whether you have these options, you can ask your BMW dealer to run a VIN check for you, which will list out all the options you have on your car. I believe there also VIN decoders available online - Google it.

I don't know if these 3 options can be retrofit - my options were put in at the factory.
