Good evening Condor,
you complicate me a life (and probably I also to you, sorry)

.
Your video: obviously you use: "snap to the road: disabled", compass source: hardware, right? (please ignore the problem with the draw of lines ... I've fixed it today).
So main problems I see:
-
shaking of rotation: phone placed vertically in some holder in the car? This rotation problem also without navigation? Quite a common problem in the car I believe, that's why you should use "Orientation via GPS" as compass source and not a hardware compass as you use. With disabled "Compatibility mode" it seems to work correctly (since 1:21)
-
"blinking" of tracks after you select new target. I see that old track remain on the map ... seems to be an issue as well, fixed. Anyway, this drawing of track is mystery for me to be true.
Anyone same issue like Condor on his video in 2:18??
