Hi, I'm currently running 2007-2 so I fail to see why it's necessarily related to a map update.
The other consideration is that the Congestion Zone operates from 7:00am to 6:00pm Mon - Fri so the Sat Nav should be getting info re this from the traffic satellites in order that it only navigates you around it when necessary.
Seems a little on the lame side to me for such an expensive option - then again maybe London is considered a fairly insignificant city so why bother?
Think I will contact Mini UK re this for an explanation.
Cheers, Geoff.
