 4.2.2  Traf

fi

 c settings 

The recommended route is not always the same between two points. Whenever suitable data 
exists, traf

fi

 c information can be taken into account in the route calculation. 

Button

Description

Use this switch to enable or disable historical traf

fi

 c data and traf

fi

 c 

patterns. This locally stored information can be very useful in normal 
circumstances but for example on public holidays it may be better to turn 
off in order not to take into account normal weekday traf

fi

 c jams. 

Use this switch to enable or disable receiving real-time traf

fi

 c information 

online. The rest of the buttons below are all related to this real-time 
information and are available only if receiving is enabled. 
You can also de

fi

 ne whether to receive online traf

fi

 c via the 3G network or 

only when connected to a WiFi network. 

This setting determines how the navigation system uses the received real-
time traf

fi

 c information in route calculation. When calculating a new route, 

or when recalculation becomes necessary based on the received Traf

fi

 c 

events, the navigation system avoids traf

fi

 c events if it makes sense. 

You can also set the minimum delay that triggers route recalculation, and 
you can instruct the application if you want to con

fi

 rm every recalculation. 

When setting a route in consideration of traf

fi

 c information, a time 

setting is available which indicates the amount of possible time savings 
obtainable by making a detour.
