Zozman,
I don't know about the iPhone connectivity, but a friend of mine has a U.S. spec 5 series bought here in Germany. There was an issue with the nav and the European maps were not available. As a fix the dealer gave him a USB drive with the maps on it and it works, so it seems like that may work for you also.
