Hi Gerd, for GMapTool to set first flag, all tiles should include DEM.
I'm afraid, that mapset with mixed tiles - with and without DEM - is not standard for Garmin. It might be impossible to invent a proper way to handle that configuration.
Some years ago I did a number of tests and chose the most safe way to set both flags. I remeber, that some arrangement of tiles and flags can cause errors for Mapsource, but I'm not able to directly give examples. Unfortunately I don't remember now, what was the reason for GMapTool algorithm.
