After using the normal version i started over with the mod version it feels like a huge upgrade there is still one thing that seems broken the speed indicator at the bottom (center) only shows the maximum speed the gps speed does not show.
First i thougt that it was my android radio but i tested it on a samsung galaxy J5 that shows the same, is this not functioning properly in this version or is there a setting witch is set wrong.

The tt manual does not say anything about this.
