Recalculate
This function repeats the route calculation based on the same settings as used to calculate
previously. This possibility is typically used when automatic off-route 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 ASUS GO 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.
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 ASUS GO 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 ASUS GO 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.
