4.7.3 Route tab
This menu contains options to manage different settings in the program.
4.7.3.1 Recalculate
This menu point is only available if an active route exists and GPS position is
present.
It brings up a menu with four options. Using one of these functions you can modify
the current route.
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 Uniden Navigation 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 57).
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 Uniden
Navigation 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 Uniden Navigation
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.
