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.

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

The road network is indicated in extremely simplified form.
Guidance is the generation and output of driving recommendations, in order to guide the driver to the desired
destination. The prerequisites for route guidance are:
Permanent location finding is in operation (is accomplished automatically),
destination has been entered and
the route has been calculated.
The navigation processor permanently compares the data from route calculation with the data from permanent
location finding using this information for measures for further guidance. Two route guidance operating modes
can be distinguished depending on the vehicle position (see figure):
Guidance within the digitized CD-ROM map area.
Limited guidance outside of the digitized CD-ROM map area.

The data is determined by the navigation processor and transmitted to the radio and navigation module
(A2/56) The current route guidance is primarily supported by the voice output (English).
The scale of the displayed map can be changed in increments. In addition it is possible to select whether the
map is aligned in the direction of motion Head-Up ) or toward the north North-Up ). The graphical signals for
map illustration is generated by the navigation processor.

When traveling outside of the digitized map area (e.g. company grounds, parking buildings, dirt roads,...),
however still within the DVD map boundaries, the navigation processor switches over to "navigation system in
non-digitized map area".
On the radio (A2) display the following message appears:
"OFF ROAD"
If the vehicle is also outside the DVD map limit, the following message appears:
"OFF MAP"
In both cases, only basic location finding is accomplished with correction using the GPS data.
A (limited) route guidance can be conducted only with specification of the:
Distance from the destination as the crow flies
Direction to the destination (as an arrow)
After reentering the digitized map area, the system automatically continues with "navigation system in digitized
map area". The possible streets/roads on which the vehicle may be located are determined with the aid of GPS
location finding. During this process a slight delay in the route guidance may result.
The road data of several Central European countries are stored on the navigation DVD, so that the "OFF
MAP" message will not appear, if borders between the stored countries are crossed. No special foreign country
DVD has to be inserted.

Fig. 55: Identifying Dynamic Route Guidance Function
Starguide was developed on the basis of dynamic route guidancein Europe. In order to comply with the more
comprehensive USA requirements this system also contains an additional Information Service specially
adapted to specific user requirements.
Dynamic route guidance
The desired requirements are transmitted to the S ervice O perating C enter (SOC ). The Service O perating C
enter (SOC ) transmits the individual and relevant traffic situations to the vehicle in the greater metropolitan
area of Los Angeles.
The current route guidance and the calculation of the dynamic route guidance is accomplished by the navigation
processor in the radio and navigation module (A2/56)
Moreover, traffic jams and construction sites are indicated on the radio and navigation module (A2/56)
display in form of icons .

The current traffic situation is taken into consideration in the dynamic route guidance. The COMAND
navigation system Audio 30 APS can receive information on the traffic situation either by the Traffic Center
Service (TCS) or the Traffic Message Channel (TMC).
The services from the Traffic Center Service (TCS) are offered by an external provider and an application is
to be sent to the provider for use.
Traffic messages via Traffic Center Service (TCS)
The latest traffic situation information is transmitted by a service provider for a fee in the form of an SMS (short
message service) signal via the CTEL D network. The traffic data are only transmitted when the service
provider receives a corresponding request from the vehicle.
The request can be sent either:
Cyclically, every 15 minutes
Once
In order to reduce the data volume the current location of the vehicle is automatically sent to the D network
center when the information request is posted.
The service provider then transmits only traffic messages at within a radius of approx. 75 km of the vehicle. The
telephone system of the vehicle receives the traffic announcements and transmits them via the D2B to the traffic
data recorder that is integrated in the radio (A2).
It is possible to use the telephone during TCS data interchange.
Traffic messages via Traffic Message Channel (TMC)
Information on the current traffic situation is transmitted by a specially equipped radio-broadcast station aimed
at specific areas and coded (toll) or uncoded (toll free) via VHF. For this purpose an appropriate FM/ RDS
station must be tuned in.
The radio (A2) receives the traffic announcements and transmits them to the traffic data recorder. Since no
communication is accomplished between the vehicle and broadcasting corporation with TMC messages, the
traffic data recorder selects the traffic messa
ges related to the route on which the vehicle is presently driving as
