Once the destination is entered into the radio (A2) the route is calculated by the integrated navigation processor
and constantly updated. This can only be calculated within the digitalized map areas. The calculated route is the
prerequisite of the destination guidance system.

Route calculation, function

The navigation processor calculates the route based on the entered destination and with the aid of the DVD map
data while constantly finding the location. In the calculation, it takes into account the roads and attributes
available on the DVD card and their attributes, such as one-way streets, bans on turns, road classes, etc. (where
present).

Additionally, it is possible for the operator to indicate how the route is to be calculated:



Fastest route



Shortest route



Own adjustments

In the event of "OWN ADJUSTMENTS", the following stretches can be blocked from the route calculation:

After calculation of the route, the navigation processor makes up a list of the streets along the route. This route
list is used for navigation. It can be displayed during navigation by pressing the "I" (INFO) and "RTE" (Route)
buttons.

Route updating

If the driver deviates from the calculated route, a new route list is automatically calculated by the navigation
processor. The current position and the direction of travel are taken into consideration, and the new route is
optimized accordingly. This is accomplished without any message on the display.

Circumventing traffic jams with "Traffic jam" menu key function

After a traffic jam is reported on traffic radio and before reaching the affected section, a route can be calculated
for driving around the traffic jam. For this purpose, activate the "Traffic jam" menu and enter the length of the
traffic jam including the distance to the start of the traffic jam.

The "Traffic jam" function is also available for Federal and State highways as well as for inner city areas.

Trips outside the digitized map area

If the vehicle leaves the digitized DVD map area (e.g. driving into a multi-level car park), then no route can be
calculated or updated. "OFF ROAD" appears on the display. Upon leaving the map boundary, the display "OFF
MAP" appears.

Destinations which lie outside of the digitalized map area cannot be taken into consideration on calculation of
the route.

The route is calculated and updated continuously by the navigation processor after entering the destination on
the radio and navigation module (A2/56) It can only be calculated within the digitized map area. The
calculated route is the prerequisite of the guidance system .

Route calculation

The navigation processor calculates the route with the aid of the CD-ROM map data, the entered destination

and the momentary position. When calculating it considers the roads and attributes such as one-way streets,
turning prohibitions, street classes,. (if present) read in from the CD-ROM map. Thereby it is possible for the
user to determine in which way the route is to be calculated:



Maximize freeways



Shortest route



Minimize freeways



Minimize toll roads

Following route calculation the navigation processor sets up a list of the roads and junctions to be taken. This
route list is used for guidance. It can be displayed by calling up the menu " LIST ".



Route updating

If the driver deviates from the calculated route, a new route list is calculated by the navigation
processor. The current position and the direction of travel are taken into consideration, and the
new route is optimized accordingly. If the driver wants to deviate from the route, the calculation
processor calculates a new route by pressing the multifunction key "DETR " (detour).

On freeways the newly calculated route starts within approx. 5 miles and on highways within approx. 1 mile ".



Detouring traffic jams, construction sites with "Avoid Road " function.

When approaching a traffic jam, a construction site etc., it is possible to set up a new route calculation
detouring the hindrance before the reaching the corresponding route section.

For this purpose press" NAVI MENU " button. Select "Route" with the aid of the" joystick " and then select"
Avoid Road ". Select road to be avoided in the list displayed then.

If more roads are to be avoided proceed with " Continue to Avoid Roads ". If the newly calculated route is
acceptable confirm with " Reroute ". Then confirm in " Continue Trip to " menu with Enter.

Fig. 52: Identifying Digitized DVD Map Area And Non-Digitized DVD Map Areas

Navigation is the generation and output of driving recommendations, in order to guide the driver to the desired
destination. The prerequisites of destination guidance include:



Constant map matching is in operation (occurs automatically),



Destination was entered



Route has been calculated.

The navigation processor continuously compares the route calculation data with the ongoing location finding
data and derives from this measures for further navigation.

The navigation processor is integrated in the radio (A2).

Depending on the vehicle position, a distinction is made between the following navigation modes:



Destination within digitized DVD map area



Restricted navigation outside the digitalized DVD map area
