It was a challenge to figure out if I could get it to work because the dealer codes mean nothing really. I ended up pulling the radio out and checked to make sure it had the fiber optic connections on the back. Apparently BMW has a professional radio that looks the same from the dash side, but doesn't have the fiber optic connections. Mine luckily had the connections and mObridge assued me it should work, which it did.
If my car didn't have the iPod interface or Bluetooth, then I would look into replacing the whole head unit. Parrot is making a really nice head unit that has iPod integration, bluetooth, Nav, Pandora, etc., that looks pretty cool. Also there are dash kits that look like a perfect fit & you lose the ugly CD slot in the dash too.
It makes a big difference when you commute 2 hours a day to be able to answer calls easily and it sounds good. People all say the Parrot mikes with my kit sound really good, so I am not regretful about spending the money on the mObridge kit. However I now look at the Parrot Asteroid and kind like the ability to have all the integration with the smartphone right in the dash & it's better than the BMW iDrive interface.
Good luck!
