I prefer to have Basemap - but I know many people delete it by accident or don't activate it - and I just tried a gmapsupp DEM map will also give shading to overview map. And yeah - maybe call it --dem-empty-dist so you would have e.g. --dem-dists=19884,39768,53024,106048 --dem-empty-dist=212096 or --dem-dists=19884,39768,53024 --dem-empty-dist= 106048 not sure what values will work best. And yes I would expect only uknown or undefined heights should do the trick - but of course I do not know. With garmins usual approach i do guess it's possible to create it in a way that it switches off at some zoom level by inserting empty data.

Hi Felix,
it should be easy to add an empty layer, but I'd prefer a special option for that. Any ideas for a good option name? I guess an empty layer would be one that contains only "unknown" or "undefined" heights. No idea what the device will do with such a layer, I'll try it. If I got you right you prefer to have no basemap on your device? Or maybe some devices don't have one by default?

If compiling DEM gmapsupp.img for device, right now it will show forever when zooming out - it would be good to have a fake/empty dem top layer - say --dem-dists=19884,39768,53024,212096 with 212096 being empty or just having enough data that the device is not actually shading the map?
Basically I think dem on device is only useful from around 5-30km zoom levels (with default detail level). 5km is the lowest that the devices choose if DEM is on auto zoom level, but it will continue showing it indefinitely (at least if no basemap is activated) - so getting the device to show an empty dem to switch of shading would be pretty useful.
