Also without show-profiles=1 MapSource and BaseCamp don't use DEM for elevation of waypoints. Basically it's only used for routing and showing the shades.

No, if show-profiles = 1 and DEM data is present, the profile is calculated from the DEM data and *not* from the contour lines


If DEM data (see "Hill Shading (DEM) options") is available the flag  changes the status line to show the height when you hover over an area with  valid DEM data.


Agree

Maybe add a remark that if show-profiles = 0 and DEM data is present, an elevation profile is always  available?
