If that’s the case, it can (very possibly) only mean one or two things:
1. That for whatever reason the detailed map (or at least the detailed map segment) was not present or not activated or simply not selected (ticked)
2. The motorway wasn’t shown on the detailed map
I would suspect option 1.
Before you start downloading stuff again. Go to settings and make sure the map set is ticked. From memory: Home screen, spanner, navigation, scroll down, map details.
Then go to the map screen, scroll about in Germany, Spain, Finland and the UK zooming in and out to see if the detailed (small) roads are shown. Report back what you find.
