Generate turns
Turns in advance: each generated turn is placed this far before the junction, on a new route point, so the watch announces it earlier. It is shortened so that it never comes before the previous junction. 0 = at the junction.
Fork sensitivity: how far apart two ways may lead for a “keep left / right at fork” instruction. Low = only narrow forks, where the ways are easy to confuse (within 40°); Normal = within 60°; High = also wider forks (within 75°). Where a fork doesn’t qualify, no instruction is added.
Bear sensitivity: where the route bends by 15–45° and another way goes off more sharply to the same side, the route is the gentler of the two and gets “bear left / right”. Low = only if the other way is within 40° of the route; Normal = within 60°; High = within 75°. Otherwise no instruction is added. Without road data, “bear” depends only on the bend of the route. Press Generate turns again after changing either sensitivity.
Generate turns decides from the shape of each junction: no instruction where the way clearly goes on, “keep left / right” or “straight on” where similar paths split, a turn where the route really turns. It replaces the turn, fork and straight-on waypoints; roundabouts, points of interest and start/end are kept. Road data are stored in this browser for 30 days.
An experiment: after the turns are generated, every turn gets a waypoint of the type Crossroads with the same name as the turn (for example “Turn left”), exactly this far back along the route from the turn waypoint. 0 m = at the same place, right after the turn in the file. The watch may then show the distance to the next turn in the field for the distance to the next point of interest / waypoint, while the turn-by-turn navigation keeps working. Press Generate turns again after changing it.
