GF82.85-P-2012LE Navigation Mode, Function



GF82.85-P-2012LE Navigation Mode, Function
- with CODE (530) COMAND APS USA (with navigation system)
- with CODE (527) COMAND APS with single DVD drive (with navigation)


Function requirements, general
^ C. 30g ON or c. 15R ON
^ Cockpit Management and Data System (COMAND) authorized and working correctly
^ Signals from at least three Global Positioning System (GPS) satellites present

Navigation mode, general
The navigation module is integrated into the COMAND controller unit (A40/3).

The navigation system includes these functions:
- 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 in the "Destination" submenu:
- Country (without code (494) USA version) or state (with code (494) USA version)
- Place name
- Road
- Intersection or house number (depending on the availability of the data)
- Town center
- ZIP code
- Point(s) of Interest (POI))
- 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 options can be selected in the "Mode" submenu:
- "Fast route"
- "Dynamic route"
- "Short route"
- "Avoid freeways"
- "Avoid toll road"
- "Avoid toll sticker roads" (without code (494) USA version)
- "Avoid tunnels"
- "Avoid ferries"
- "Avoid routes involving car transport by means of other vehicles"

The navigation module is used to calculate the data for reaching the destination (navigation) from the data entered.
To this end, the navigation system is equipped with the following functions, which are described in separate documents:
^ Position finding and destination-oriented navigation, function
^ Route guidance through voice output, function

Function sequence for navigation mode
The route is calculated in accordance with the options set. If it should not be possible to adhere to the options, then the configured options are ignored for the stretch in question and a corresponding message is output visually as well as acoustically. The set criteria and options can be displayed and changed at any time. After successful computation, the route is displayed on the map in the COMAND display (A40/8) (without code (867) SPLITVIEW) or on the SPLITVIEW display (A40/10) (with code (867) SPLITVIEW) and additionally via arrow pictograms in the multifunction display (A1p13) of the instrument cluster (A1). Additionally, the acoustic message "The route is calculated" is output.
If the vehicle is no longer moving on the precalculated route, the route is recalculated. If the recalculated values are plausible for the navigation system, then the modified route is displayed. The corresponding signals are transmitted via the central CAN (CAN F) to the instrument cluster.

Dynamic route guidance
The dynamic route guidance takes the current traffic situation into consideration.

The navigation system can be operated using the following controls:
- Left multifunction steering wheel button group (S110) and right multifunction steering wheel button group (S111)
- Front central operating unit (A40/9)
- Voice control system (VCS [SBS]) (up to 31.5.09 with code (813) Voice control system (VCS [SBS]) and as of 1.6.09)

The control signals for the multifunction steering wheel button group are made available as follows:
- Steering LIN (LIN E1)
- Steering column tube module (N80)
- Chassis CAN (CAN E)
- Central gateway control unit (N93)
- Central CAN
- COMAND controller unit

When entered using the front central operating unit, the control signals are forwarded via telematics CAN to the COMAND controller unit.

Voice input is made over the handsfree system microphone group (A67b1).

In vehicles up to 31.5.09, the voice commands are read in by the voice control system control unit (VCS [SBS]) (N41/3) (with code (813) Voice control system (VCS [SBS]) and forwarded via Media Oriented Systems Transport (MOST) to the COMAND controller unit.
In vehicles as of 1.6.09, the COMAND controller unit reads in the voice commands directly.

Updating the map data:
The map data are installed on the hard disk of the COMAND controller unit. To install new map data, they must be copied from a navigation DVD.

This procedure should be performed while the vehicle is standing if possible. To prevent the on-board electrical system voltage from failing, the engine should be running or the vehicle should be supplied with external power. After inserting the navigation DVD into the COMAND controller unit, a prompt automatically appears asking whether the map data is to be installed.

For privacy protection reasons, an activation code must be entered before installing new map data.

After its confirmation the installation is started (t = 10 to 120 min). Navigation is not possible until after the installation is complete. If an installation procedure is interrupted, navigation is no longer possible and the installation procedure must be repeated. After successful installation, a corresponding message appears and the DVD is ejected automatically.
