If you are traveling along a route and you need to stop by to see something and then return back, then there are serious errors with the navigation commands. I came across this situation a few days ago when I was cycling in the bitter cold. Since the phone's battery runs out quickly in the cold, I decided to put the phone in my pocket and follow the voice commands of the navigator.
Here is my route: http://tinyurl.com/26nke6cb .
When I was at the point "78 km to the finish line", Locus gave me the command "turn left after 300 meters", but at this point there is no road to the left. In addition, the "go straight" command is displayed at this intersection. I was driving straight. When I returned and approached the same intersection, the Locus was silent, although I was waiting for the command to "turn left". And I was driving by until I heard the command "You're off the route." This situation has been repeated in every such case.
There I also drew a small test route "78 km to the finish line": http://tinyurl.com/a2vxfytm and the locus at this intersection has already set the waypoints differently, and these points are also wrong.
As a result, it is completely unrealistic to use voice navigation commands, they are misleading.
In addition, routing in the scheduler also occurs with incorrect routing points.
In addition, I found that in test mode (when GPS is disabled), voice prompts are not voiced when driving along the route, previously it worked exactly.
Tested on versions of Locus Map 3 Classic 3.68.2 3.69.2 3.70.3 3.70.4
If my explanations are unclear, I can record a video.
