Circular routes
-
In my trips that I have done since I have been using the Navigation Next app I had the impression that the app did not handle circular trips well today I had confirmation of this, given the beautiful day I organized a quick trip near home, a circular trip of about 150km, about 10km from the start I had to make a detour to get gas (where now there is waypoint no. 2 that was not there before), once I returned to the main road I expected to continue navigation towards point 3 instead the app wanted to make me go back, thinking I had skipped a waypoint I looked for the command from android auto to skip waypoint and I did not find it (does it exist?), so I had to stop and take the smartphone and I discovered that the next waypoint was not point 3 but point 9 basically at the end of the route, making me take the shortest route from where I was and the end completely ignoring the subsequent waypoints.
I continued the trip to point 3 and deleted waypoint no. 9 and so I was able to resume navigation correctly up to point 8.
This is the tour I did: -
@ginogino, The way you describe this is completely like the logic is programmed. When you deviate from the route (at WP2, to get gas), it takes 3 calculations to auto skip WP3, which in your case is 27km further in the route. It looks at the next 10 waypoints and decides which one is closest (calculated over the roads). If you just past WP2, it is not hard to imagine WP9 is closest, so it takes that one. This is exactly how the algorithm is intended. The real problem with the route is the lack of waypoints.
If you deviate from a route to have a stop (whether gas, lunch or whatever), recalculations will occur. It is wise to look at the route before taking off again. You do not have to delete any waypoints, just long-press WP3 in order to set that as the new first WP to drive through.
