I pondered weather to upgrade the 2005 SatNav disc to a 2010 version. And in the end I did from ebay of course.
It also came with a Major Roads of Euopre disc too.
Excitingly I put the disc into the mach and waited. After an intial delay it came on.
the maps are better now and traffic management redirect system fully functions. I ponder if it knows where Rog lives now?
