Maybe the 'DEM' you are seeing is the in-built DEM on the basemap showing when you zoom out. Please read my previous post again, the EU 3D Terrain DEM works for me as stated. I agree with dasilvarsa, if it's not showing in MyMaps usually it's not active, but don't forget the bug which often will combine and confuse the info if 2 or more DEMs are loaded. To cover all bases, I moved the EU DEM D2249750A.IMG to the unit's .System folder and renamed it gmapdem.img. It's still selectable in MyMaps identifying as 'Europe DEM' and it's working normally. gmapdem1.img should also work in .System folder.

Map identifying as '3D' are 3D building/landmark maps, 3D Terrain maps identify as DEM in MyMaps.

Just so you're clear on what I was saying, the 3D Terrain selection in Map Layers disables DEM totally. The selection in MyMaps is for individually selecting/deselecting separate DEM maps.
