Navigation mode, general
The navigation module is integrated into the COMAND controller unit (A40/3). The navigation system includes the following functionalities:
- Position determination
- Route planning, route calculation and destination-oriented navigation
- Visual driving instructions in form of pictograms
- Intersection zoom
- 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 or federal state (with code (494) USA version)
- Place name
- Road
- Intersection or house number (depending on the availability of the data)
- Town center
- ZIP code
- Special destinations
- Destination entry via 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 parameters can be selected in the "Mode" menu:
- "Short route"
- "Dynamic route"
- "Fast route"
- "Eco route" (as of 1.6.2010)
- "Avoid freeway"
- "Avoid toll road"
- "Avoid tunnels"
- "Avoid ferries"
- "Avoid car trains"
- "Avoid roads requiring toll stickers"

In the "Points of interest" menu the "In destination area ", "Current position", "Other location" and "Search using names" menu items are supported. After entering or calling a destination location, route calculation starts. The following POI categories have been defined:
- "Active sport"
- "Pharmacies"
- "Car rental"
- "Railroad station"
- "Bank"
- "Library"
- "Embassy"
- etc.

The system can be activated or deactivated or the destination and street can be entered using the following components:
- Left multifunction steering wheel button group (S110) and right multifunction steering wheel button group (S111)
- Audio/COMAND control panel (A40/9)
- Control panels on the COMAND controller unit
- Voice control system (VCS [SBS])

Navigation mode
The navigation processor integrated into the COMAND controller unit calculates the data entered for reaching the destination (destination-oriented navigation). Further subfunctions are described in separate documents:
^ Position finding and destination-oriented navigation
^ Route guidance through voice output

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. Once calculated, the route is displayed using arrow pictograms in the Audio/COMAND display (A40/8) and this information is also issued as an acoustic notification: "The route is 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.

Dynamic route guidance: An alternative route is offered under dynamic route guidance if there is a traffic jam or a road block on the calculated route.

The signal path for the control signals of the left multifunction steering wheel button group and the right multifunction steering wheel button group to the COMAND controller unit is as follows
- Direct line
- Steering wheel electronics (N135)
- Steering LIN (LIN E1)
- Steering column module control unit (N80)
- Chassis CAN (CAN E)
- Instrument cluster (A1)
- Interior CAN (CAN B)
- COMAND control unit

When entered using the Audio/COMAND control panel, the control signals are sent via the telematics CAN (CAN A) to the COMAND controller unit. When entries are made via the control panels on the COMAND controller unit, the control signals are processed within the unit. Voice input takes place via the hands-free system microphone (A67b1).

Words spoken into the hands-free system microphone are converted into an electrical signal and forwarded via a direct line to the COMAND controller unit.

For the voice control of the navigation, in particular for destination entry, additional name lists are available in the system.
The following lists are available for the voice control system:
- List of place names for selected towns on the data storage device
- Street name list for all towns/villages
- List of the relevant intersecting street
- Town center list

Updating the map data
The map data is installed on the hard disk of the COMAND controller unit. In order to install new card data, this must be copied from a navigation DVD. This procedure should be performed with the vehicle at a standstill, where possible. To ensure that the on-board electrical system voltage does not run down, the engine should be running here or the vehicle supplied with external voltage. If the navigation DVD is inserted in the COMAND controller unit, a prompt automatically appears asking whether the map data is to be installed.

Following confirmation that the map data is to be installed, the installation takes place (t = 10 to 120 min).
Navigation is only possible following complete installation. If the installation procedure is interrupted, it must be continued and completed. Following successful installation, a corresponding message appears and the DVD is automatically ejected.
