Forgive me. I'm still a little confused. Is there a way for me to get whatever parts are necessary to fully integrate my 3G iPhone into an X5 that didn't come from the factory with the "Smart Phone Integration"? Here is a part that sounds like it does everything I want;

Apple iPhone USB Snap In Adapter

The problem I see is that it mentions the Smart Phone Integration being required. Can that be added? I have the BMW Assist and Bluetooth.
