Did you pair it with bluetooth? Here's a few additional thoughts.

You can turn Notifications on in the Bluetooth pair settings on the phone itself after pairing no problem. The capabilities aren't locked in during the initial pairing, they're renegotiated every time the devices connect. That's why you can toggle BT Audio on and off on iDrive for example without deleting and recreating the whole phone profile. So you may have to. Other than that O have no clue i'm just guessing. Perhaps a windows phone and an iPhone cannot reside on the system at the same time.
