I had an 06 disk but upgraded to an 07/08 Ver 1 disk. It was the Western Europe disk of a four disk set as I remember. Got it off ebay then sold my old one. In the end the difference was less than £10 ;-)
Not bad.
Anyway, if you give me an example of something/somewhere you want to find on the disk I'll go try it. I just checked the coverage menu and it shows GB, France, Protugal, Italy and Spain etc have detailed coverage. The Eastern fringes like Germany show coverage but not detailed.
