General
Navigation mode is an assistant function which supports the driver in reaching his/her destination without diverting his/her attention from traffic. This is done by:
- Route planning, route calculation and destination-oriented navigation
- Visual driving instructions in form of illustrations
- Intersection zoo
- Acoustic driving recommendations
- Display of navigation maps

The location of the vehicle and the direction and distance to the destination are determined with the aid of the navigation system. The navigation system consists of several subfunctions:
^ General navigation mode function sequence
^ Position finding and destination-oriented navigation
^ Route guidance through voice output

The "Position finding and destination-oriented navigation subfunctions along with route guidance by voice output are described in separate documents.

Operating instructions
The navigation system can be operated using the following components:
- Telephone/navigation quick select button (40/9s5) at the front central operating unit
- Voice control system (VCS [SBS])

General navigation mode function sequence
The navigation processor integrated into the COMAND controller unit calculates the data entered for reaching the destination (destination-oriented navigation). The route is then calculated taking the configured options into consideration. 5 routes are calculated and then displayed:
- Recommended route
- Toll roads preferred
- Avoid toll roads
- Shortest route
- Alternative route

The user can decide in favor of one of the routes and start the destination-oriented navigation. 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 dynamic destination-oriented navigation can be used for each route option. In doing so, the VICS control unit (A2/37) calculates the route taking traffic information into consideration.

The voice input takes place via the hands-free system microphone group (A67b1). Words spoken into the handsfree system microphone group are converted into an electrical signal and forwarded via a direct line to the COMAND controller unit.
