Out of route notification & Navigation along a route
target - XC bicycle . Navigate a track without a screen with only voice commands.
there are situations when it is useful to confirm that you are on the track. examples:
1) after making a turn for which a long straight section;
2) after you have shifted from the track, and then returned to it;
3) when driving on a long straight section of the track.
suggestion: add a setting to Out of route notification & Navigation along a route "confirm standing on track" with the following settings: on/off; after making a turn - on/off; long straight section - on/off; single/repeat; repeat time per second.
if you take it to work, I am ready to write in more detail.
