Well the iPhone isn't the best at grabbing a poor signal (any phone with it's antenna hidden inside it is going to be a compromise) but coverage is generally good in the UK now except in very rural areas.
The BMW connection to the iPhone (for the antenna) is only inductive, i.e. there is a flat printed coil in the snap in adaptor that lays against the antenna in the back case of the iPhone. There is a amplifier (BMW call it a compensator) in the lead between the snap in and the external antenna. I suspect the gain from the amp and the outside antenna just about adds back what is lost by the inefficient inductive coupler and the antenna cable length.
What I was a bit surprised at was the fact that my Audi with the same system design seems to provide more signal.
