Updated mine without hitch.
Locally I have an issue with the mapping though. When I am trying to come home from the north, Sat Nav now tries to send me across a local hotel car park and on to a cul de sac. This would be an illegal maneuver however you can't even attempt it as the hotel has a double decker bus parked across the back exit from the car park.
I contacted BMW who helpfully sent my email onto someone. However, my email didn't give specific details about where the mapping is wrong. :roll:
Not sure how that will work out .
