Navigation mode, function - GF82.85-P-2012GH

MODEL 163 

Function 

The navigation system is integrated into the COMAND operating, display and control module (A40/3)  . The location of the vehicle  and the direction to and distance from the destination  (according to specified destination) are determined with the aid of this system. Afterwards the required measures for reaching the destination are initiated (destination finding)  .

The navigation system is activated by pressing the " NAVI  " button on the operating unit.

A navigation processor  with CD drive  for the digital map data is integrated in the COMAND operating, display and control module (A40/3)  .

The navigation CD  drive can also play audio CDs  .

Note in Navi-CD screen  :

"Please insert Navi-CD type DX  "

Destination entry 

Destination input is performed menu-guided on the operating unit and processed by the navigation processor  . Only destinations that are also on the CD-ROM  may be entered. The COMAND operating, display and control module (A40/3)  provides the following destination input capabilities:

• Address...
• Destination memory...
• Destination using map...
• Special destinations (e.g. railway station, airport etc.)
• Travel guide...
• Intermediate destination entry
• Destination memory with individual destination designation capabilities
• Final destination...
• Dynamic route calculation by:
  • Blocking of route sections (traffic-jam function)
  • Traffic-jam ahead
  • Blocking in route list
• Incorporation of traffic information of an external service provider via telephone TCS  (once, cyclic every t=15min.  ). Chargeable services.
• Incorporation of traffic information via RDS broadcast (TMC  ), free of charge

Predictive speller (editor) 

During the entry of the destination the missing letters are augmented for an available list. This is only active in the political index  and relates to the destination  and road  entry as part of the destination finding. In the menu Special destinations  the submenus" Bypassing other locations...  " and "National destinations...  "are assisted.

The "Supraregional destination...  " menu is divided up into additional submenues. The individual menu points  in this submenu use the political index  .

Dynamic addition 

implemented during manual entry of the destination. During the entry of the destination the missing letters are augmented for an available list. The added letters are highlighted in black. Deleting is done one character at a time.

Position finding 

COMAND  continuously calculates the location of the vehicle with the aid of the following procedures:

• GPS  position finding
• Basic  position finding (compound position finding)
• Map-supported  position finding (map matching)

The navigation computer  calculates the most probable position by continuously comparing the position-finding results returned by these three methods.

Route calculation 

The route is calculated by the navigation processor  after entering the destination, or automatically, after a deviation from the suggested route has taken place.

In the dynamic destination-finding system  the route calculation is automatically influenced by the incorporation of traffic information, free of charge via RDS, TMC  or over an external provider TCS  by telephone (chargeable).

The calculated route is stored in the navigation processor  .

Destination-finding system 

Destination finding is started once the navigation computer has performed the destination calculation.

Three display options are available for graphical representation of the destination-finding system:

1. with map
2. with map and symbol display before turn-off point

   → MIX mode

3. with symbol display only (route guidance symbols)

Any of the three methods can be used. The destination-finding system is also supported by voice output  from the vehicle loudspeakers.
