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 a motorway 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. 

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. 

  

Precondition: The navigation system is in navigation mode and 

the map is being displayed.  

1. Tap the Additional functions icon. 
2. Tap Block road. 

The B

 screen opens. 

3.  Enter how many miles (from your current position on) you 

want to block. 

4. Tap OK. 

This forces a recalculation of the route. The indicated route 

section will be evaded. On the map, it will be highlighted on 
red. 

 

  

1. Tap the Additional functions icon. 

 

2. Tap Unblock. 

The route section is now unblocked. The navigation system 

uses the route, which had been calculated originally.
