So Garmin has made ​​a mistake with this new firmware upgrade, or it is the beginning of a further security methodology
I just visited this Dutch forum: this specific map (FID=10140) is larger than 4Gb and is meant only to be used in Basecamp. The separate EU maps are reported to work correctly.

As far as I can judge at the moment all (Topo) maps except CN are working.
