Thanks, both of you.

Jochen,

With the aid of this marvelous forum, I did infact upgrade my software just recently, without any problems. I went from V.23 to V.28.

I guess you have a point by saying the map data may be the same on the Scandinavian CD compared to the Euro DVD, so I think I will go for a DVD-upgrade instead of a CD-upgrade. Then I won't have to worry about reading speeds, either.

Thank you!
