This is nice feature it only needs to be fixed. My understanding is that Edge should show below the map elevation profile of the course and current rider position. Also progress along the ride. Currently on 3.50 no matter if I ride on flat terrain or in mountains is showing green flat profile. Moreover my marker is in the same middle place on the profile and not moving. Unless I don`t understand something or this is supposed to work otherwise this is a bug in the firmware.
