Guidance
Plan Alternative Route
You can have the navigation system plan an alternative route for a selectable
distance during guidance.
Use this function, for example, if you want to avoid a traffic jam or if you
do not agree with the currently planned route.
The alternative route will be calculated for the specified distance from the
present car location.
— Press the ALT-R-button.
If you want to change the value for "Distance" (route distance for which an
alternative route is to be planned; adjustable between 1 and 6 mls):
— Select the value under "Distance".

(−1) or
(+1).
— Press the OK-button.
The entered value is now stored.
— Now select the "Yes" option.
The system calculates a new route within seconds.
Calculated travel time and time of arrival
The navigation system uses the factory-set mean cruising speed of a standard
passenger car in order to calculate the remaining travel time and the estimated time
of arrival. If the times indicated in the status line (arrival time and / or remaining
travel time) significantly deviate from the actual values, then you can change the
average speed (see the following section). This may, for example, be necessary if you
are using your navigation system in a commercial vehicle or RV.
Adjustment of average speed
— Select the "Settings" function in the "Start Menu".
— Select the "System information" function in the "System Settings" menu.
— Select the "Speed correction" function in the following menu.
A sliding control for the correction factor appears (50–150 %).

The value for average speed is now changed, the remaining travel time and the
estimated time of arrival are recalculated accordingly and, depending on the setting,
displayed in the status line.
