The voice guidance in navigation mode (bicycle) always fades to zero after some time. First it starts that the voice only reaches 'in 50 meters', later 'in 50', and finally there is no voice guidance at all! Sometimes it recovers later even from a former hopeless state though...
I'm experiencing this only in bicycle mode. Calculation is done via BRouter.
I created the route with locus (partly calculation with BRouter, partly changing points and recalculation with BRouter).
