BMW have just got back to me and said " not all but some 2012 builds after september
have a Sat-Nav glitch showing thr traffic congestion on the wrong side of the roads
this makes the system useless.
At this moment in time they have no answers and have escalated the problem to the "highest level", what ever thats supposed to mean.
No updates available as yet so my £2K Nav system is F**king useless.
