4.4.3 Blocking a route section
Blocking a route
section manually
You may block a route section manually in order to evade it.
Manual blocking forces a recalculation of the route.
Presume that you are driving on an interstate and a radio
message announces a traffic jam of 4 miles near your current
position. With the “Block route sections” function you may
instruct the navigation system to evade the announced traffic
jam.
Notice: If your GPS receiver disposes of the TMC module,
OnCourse Navigator notices and evades obstacles concerning
your itinerary automatically.
A manual blocking is only valid for the current navigation
process. The respective route section will be unblocked for the
next navigation or when you restart the software.
