Hi there, yes in synch's fine, but on my E53 I can't make a call by selecting a number on SatNav and using either satnav control or steering wheel control - I have to initiate the call via the handset.......which is pretty useless. Its also a little flakey at reconnecting to the car if, for example, you wander back into the house to pick something up and go out of BT range........
In in all........it works........but only just.

I'm afraid I can't answer for the newer SatNav systems, which include the texting option.
