What does the button View instead?
Its a nice feature to define a userview with(out) backround map. But not as singel view only.
My old navi xplova 3 has 3 userconfigurable views, selectable by left/right button.
One is for Routing map view with speed,heartrate, cadence or so.
One is for full screen online data like speed, colored heartrate/ ranges or 6 free defined frames like LEIKR now.
One is for histogram view graphs what you like, highmeter, times, distance ...
