I have put Topo Danmark PRO without SQL folder on an SD and opened it in BaseCamp. The map shows but (as expected) there is no option to find Named Trails (no SQL folder).

I then added the file 010-D0751-02.db inside the SD:\Garmin\SQL folder and restarted BaseCamp, but still there is no option to find Named Trails. Yet, when looking at the header of the map in GMapTool, the p/n is 010-D0751-02 too. So map and .DB file are matching.

When I try the same with Topo Belux Pro, the option "find Named Trails" is available after adding the SQL folder with matching .DB file to the SD card.
Anything I do wrong or does Active Routing not work with this map and the file provided?
