I enquired at the MB parts dept today about an updated CD for the Sat Nav. The one I have is 2003 and it's already got me in quite a mess on a few occasions! Apparently there isn't an updated CD anywhere in the country so it would have to be sent over from Germany. The cost is £190. The guy at MB said the best thing to do was buy a portable one! He said they are cheaper and can be updated online. Has anyone had any success buying a new Sat Nav CD for their car? I've tried other online places but no luck. Didn't want to get a portable one when there is a perfectly good one (when updated) on board!
