Hi Chris, I've looked at this site earlier today - even took the CD out of the car to get its number which turns out to be nothing!
My disc says Europe 2004-2005 ver1 followed by 86271-70V 313, in trying to enter these details the system went bottoms up so I decided that there is no real update worth having. I have to say that my original disc only gives UK, Ireland, Monaco and another far away place, nothing on Europe at all.
