Ok, it is as expected: when I turn off the CNE, this map is visible again. The same applies for the swedish topo maps.

Can these things (layering) be somwhow adjusted in the device, or do I need to turn maps on and off? (It is not such a big deal - I have nautical maps turned on in the natical profile only, so I can have the CNE turned on in driving profile only. Anyway, navigation does not work well when topographical maps are mixed with the City Navigator maps, so they have to be turned off for routing...)
