- with CODE (528) HIGH Class USA
Navigation system
Using the COMAND operating, display and control unit (A40/3) the location of the vehicle, the direction and the distance to the destination (after entering the destination) are determined by the navigation processor (N41/1). Then the required measures for reaching the destination are started (navigation).
Once the navigation system has been activated by opening the driver door (in the background), it is immediately operational after initialization via the COMAND operating, display and control unit (A40/3).
A multistandard disk drive (can read various data formats) for reading the digital map data is integrated in the COMAND operating, display and control unit (A40/3).
After the "NAV" button is pressed the note "please load Navi CD" appears in the Navi CD screen.
Destination entry
The destination is entered menu-assisted via the COMAND operating, display and control unit (A40/3) and is processed by the navigation processor (N41/1). The COMAND operating, display and control unit (A40/3) offers in navigation mode the following alternatives for destination entry:
^ via destination memory
^ Destination entry
^ Special destinations (e.g. hospital, car park, gas station)
^ Last destination input
^ Entry of intermediate destinations
^ Address input
^ Destination with map
^ Travel guide
^ Destination memory with individual destinations
Predictive text input
When the destination data is entered the next possible letters are displayed and the letter in question can then be incorporated in the destination entry as well
Dynamic supplementation
This function is realized with the manual entry of the destination. While entering a destination the letters which are still missing are completed from an existing list. The supplemented characters have a black background. Deleting can be accomplished character by character. The following submenus are displayed in the "Special destinations" menu:
^ Location surroundings
^ Surroundings of current destination
^ Surroundings of any town center point
^ Surroundings of special destinations
These submenus are subdivided still further. The search radius is approx. 20 km, however special categories (e.g. airports) have a larger search (approx. 80 km).
Position finding
The COMAND operating, display and control unit (A40/3) continually calculates the location of the vehicle with the aid of the following methods:
^ GPS location finding
^ Basic position finding (dead reckoning)
^ Map-supported map matching (map matching)
The navigation processor (N41/1) calculates the most likely position by constantly comparing the location results of these three methods.
Route calculation
The route is calculated in the navigation processor (N41/1) after destination input or automatically after a deviation from the proposed route.
Voice output
The voice output is effective for:
^ turn-off recommendations
^ Numbered roads in the USA of Interstate, US highways and state highways
^ Compass direction in the USA (North, West, South, East)
There are further voice messages about the start and destination of the route.
Voice control system
Voice control can take place by means of letters or complete word input. Navigation starts once the navigation processor (N41/1) has carried out the route calculation. Three forms of destination-finding system display are available:
^ Map
^ Map and symbol presentation of the turn-off points
^ Symbol presentation (system of navigation symbols)
The map presentation is always controlled by the COMAND operating, display and control unit (A40/3). The system supports the following functions:
^ Navigation map
^ Position map
^ Destination map
^ Route map
^ Auto zoom
^ Intersection zoom
^ Traffic jam map
^ Car park map
It is possible to change arbitrarily between the types of presentation. The destination-finding system is also supported by voice output from the vehicle loudspeakers.
