3.4 Modifying the route
When navigation is already started, there are several ways to modify the active route.
The following sections show some of those options.
3.4.1 Selecting a new destination when already having a route: New Route,
Waypoint or Final Destination
If you already have a recommended route and you select a new destination as described in the
above sections, the application will ask you whether to start a new route, add a new waypoint
(intermediate destination) to the route or append the newly selected destination at the end of
the current route.
●Tap to plan a new route to the newly selected location. The previous destination
and waypoint(s) are deleted.
●Tap to add the newly selected location as an intermediate destination to your
route. The other destinations of the route remain intact. Note: the new waypoint is placed
among destinations to keep the route optimal. To decide where a waypoint to appear, use
the Edit Route feature.
●Tap to append the newly selected destination at the end of the route. The other
destinations of the route remain intact. The previous final destination is now the last
waypoint.
