Now i see what you meant in navit (1885).
Only in the gui "internal" the setting 3D exist, not in the gui "gtk".
Now when i click on 3D and change back to the map it is showm in 3D mode.
But the problem is that the map is veeeeeeeery slow in 3D mode. I tried
it on my pc first and it needed ~5s to drag the map from A to B. I think
the problem is that in 3D mode navit still shows all items on the map
which results in overfilling at the horizon. I attached a screenshot
from my pc which shows the problem.
I played a bit with the tilt="..." parameter in navit.xml which should
adjust the tilt of the 3D view but it seems to have no effect. Also i
can't find any parameter to adjust the viewdistance for items on the map
or the map itself which should increase the speed a great bit.
What settings do you use that it is acceptable fast when you are using
the 3D view on your freerunner?
