For the record, and I'm not suggesting this is the case here, one can still use capacitance coupling from the phone to the coax/roof antenna, not requiring an actual physical connection from a pin. I've use "through the glass" coupling antennas at much lower frequencies (the higher the easier) with success because it saved me from drilling a hole in my car.
A direct connection would likely be better as you suggest but if a cradle were "tuned" properly to the iPhone's conveniently placed external antenna (the one with the gap), it could work successfully. This is what I'm trying to find out from BMW. Thanks for such great feedback, Andy

Wouldn't you need to have the external antenna and the phone antenna really close to have "capacitance coupling"? If this is the case, would the cradle have an internal wire wrapped in the cradle casing, which connected to the external antenna?
