I regenerated them with new version and now they work again, there must 
have been some change that causes the problems though, see below.

I currently can't as my desktop is inaccessible sind last windows update 
(and 1500km away)...

Moreover with the newer mkgmap version, it seems that Draw Priority 
compared to non mkgmap compiled cards does not take preference over our 
cards anymore....
The level info is pretty strange, gpsmapedit does not find it, but 
mkgmap shows it even though the overview map consists of 4 points only....
