Function requirements
- Status "Circuit 30 ON"
- The Cockpit Management and Data System (COMAND) is switched on, authorized and operating error-free
- No fault on global positioning system (GPS) antenna system
General
The navigation module is integrated into the COMAND operating, display and controller unit (A40/3). The navigation system includes these functions:
- Position finding
- Route planning, route calculation and destination-oriented navigation
- Visual driving instructions in form of pictograms
- Intersection zoo
- Acoustic driving recommendations
- Display of navigation maps
The location of the vehicle, as well as the direction and distance to the destination are determined with the aid of the navigation module after entering the following information:
- Country, except code (494) USA version, or State, with code (494) USA version
- Town name
- Street
- Intersection or house number (depending on availability of the data)
- Town centers
- ZIP code
- Points of interest (POI)
- Destination entry on map
After entering or calling a destination location, route calculation starts. The route between the current vehicle position and the destination is calculated. The following computer models can be selected:
- Avoid freeway
- Avoid ferries or car trains
- Avoid tunnels
Moreover, additional route options can be selected for vehicles, except code (494) USA version:
- Quickest route
- Shortest route
- Dynamic route
- Avoid toll road
- Avoid roads requiring toll stickers
The submenus "In vicinity of destination", "Location vicinity", "Vicinity of other locations" and "Search with name and number" are supported in the "From Points of Interest (POI)" menu. After entering or calling a destination location, route calculation starts. POI categories are, e.g.:
- Junctions
- Highway service
- Airport
- Hotel or motel
- Hospital
- Parking lot
- Restaurant
Further subfunctions are described in separate service information:
- Position finding and destination-oriented navigation
- Route guidance through voice output
- Display compass, with code (245) Electronic compass
Operating instructions
The navigation mode function can be controlled with the following components:
- Control buttons on the COMAND operating, display and controller unit
- Voice control system (VCS [SBS])
Function sequence
When entered using the control buttons on the COMAND operating, display and controller unit, the control signals are processed within the COMAND operating, display and controller unit.
The voice input takes place via the hands-free system microphone group (A67b1). The words spoken are converted into an electrical signal by the hands-free system microphone group and routed to the COMAND operating, display and controller unit via a direct line. The data entered for reaching the destination (navigation) is calculated via the navigation module integrated into the COMAND operating, display and controller unit.
The route is calculated according to the options set. If observance of the options is not possible, then the options set are ignored for the sections in question and a message is displayed and signaled audibly. The configured criteria and options can be displayed and changed. After calculation, the route appears on the map on the display of the COMAND operating, display and controller unit and by means of arrow pictograms on the display in the instrument cluster (A1). An acoustic information feature also announces "Route calculated".
If the vehicle is no longer moving on the pre-calculated route, then the route is recalculated. If the recalculated values are plausible for the navigation module, then the modified route is displayed.
The signals for displaying the arrow pictograms on the display in the instrument cluster are forwarded by the COMAND operating, display and controller unit to the instrument cluster via the interior CAN.
Dynamic route guidance (except code (494) USA version)
An alternative route is calculated automatically under dynamic route guidance if there is a traffic jam or road block along the calculated route.
