I can see rather the same problem.

My map data seems to be more exactly, I have almost no delta between actual and calculated route.

But I get the same wrong turn informations. In previous gpsapp-versions I got it right but with 0.17 the following problem occurs:

- most of the "continue" situations are presented as "turn right" or "turn left"; they were previously presented correctly or at maximum as "bear left/right"

- sometimes "turn left" is presented as "turn right" or vice versa

Beside that 0.17 is great !
