Mio MIOMAP C220 - Manual (Page 47)

recalculation is disabled. However you may consider using it when you travel on a
road parallel to that recommended by the route. In this case MioMap may not
recalculate the route for some time, but you can force recalculation here. This is also
the button you will most frequently use when the window appears automatically,
provided that the manual route recalculation is set (Page 73).
Drop Next Via Point / Delete Route
You can modify the route to skip the next via point if you decide it is no longer
needed. For example, you may have added the via point only to influence the route
but you do not want to actually reach it; or you have already almost reached it, and
MioMap still keeps on navigating towards that point. When there are no via points left
(only the destination), the name of this button turns to Delete Route, and it cancels
the navigation.
Bypass
When you run into a traffic jam or roadblock, you may want to have MioMap
calculate a route that departs the original route as soon as it can. You will need to
select the minimum distance along the original route where your new route is
allowed to rejoin the original route. Select the one you feel appropriate for the traffic
difficulty you face.
Note: This function is to give you an alternative for the next section of the
recommended route. To change later parts of the route or to avoid specific streets or
turns, use the Avoid function in Itinerary instead (Page 48).
Note: When you use this feature, MioMap will keep on excluding the same part of the
map from later routes until you manually delete the route (Page 47), or restart
MioMap.
Cancel
This option returns directly to the map screen without recalculating the active route. If
you choose this option when manual route recalculation is configured (Page 73),
navigation stops and will be activated again when you are back on your original
route.
4.6.3.2 Delete
Tap Delete to erase the active route along with all its route points (start, via points
and destination). If you later decide that you need the same route again, you will
have to rebuild it from scratch. MioMap will warn you before deleting route data.
