Sorry guys if this has already been covered, I couldn't find anything with the search feature, but....

I've bought a car that have an MKIV DVD-system. It came with the 2005-1 "High" European DVD. I want to upgrade to a newer map software, and living in Sweden/Denmark, I found the "Scandinavian" maps to be the most relevant for me (I do not plan to drive around Europe much).

BUT... and here's the questions: apparently, the "Scandinavian" maps only comes on CD-ROM. It seems that the only available DVD-maps is the "European High" maps. But which map would be the most detailed (in Scandinavia): a "Scandinavia" CD, or a "European High" DVD? And, if you use a CD-map in the DVD-system, is there any limitations or delay in use, compared to a DVD-map?

Thanks.. , but love it already.
