I can agree the Apple/Google maps- which are continually updated- are better than the Teleatlas maps.

BUT, if you tell me it is easier to hold your iPhone in two hands and route your trip, as compared to driving with one hand, navigating with the other, while keeping an eye on the road, I'll call you on that.

Again, not in love with the BMW navigation (actually I've used it extensively in Germany, Switzerland and Holland, and it is very, very good- better than US maps) but again, integration is pretty nice.
