would be possible, do you have during navigation, in addition to the map of the track to follow, even the elevation with an indication of where we are?
something like this. perhaps with a point that represents your location

Will be wonder to know the future elevation and not the past one!
I would like to know how much uphill or downhill I have to face up
Also like data field
Thanks
