General information
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 system 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 up 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 vehicle shipments
- Avoid tunnels
Additional route options can also 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 "POI" menu.
After entering or calling up a destination location, route calculation starts. POI categories are, e.g.:
- Junctions
- Highway service
- Airport
- Hotel or motel

Function sequence
The data entered for reaching the destination (destination-oriented navigation) is calculated via the navigation system 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 system, then the modified route is displayed.
The signals are output to the instrument cluster as follows:
- COMAND operating, display and controller unit
- Controller area network bus, class B (interior compartment) (CAN B)
- Instrument cluster
Dynamic route guidance (on vehicles 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.
The system can be activated or deactivated or the destination and street can be entered using the following components:
- Control panels on the COMAND operating, display and controller unit
- Voice control
When entries are made via the control panels on the COMAND operating, display and controller unit, the control signals are processed within the unit.
Voice input takes place via the VCS [SBS] microphone (B25/7). The words that are spoken are converted into an electrical signal by the VCS [SBS] microphone and routed to the COMAND operating, display and controller unit via a direct line.
