As of 1.9.06, the location and number of microphones in the hands-free system microphone group will change as follows:

The number of microphones will be reduced from 4 to 2.
The installation location of the microphones will change from underneath to above the inside rearview mirror unit (A67).

Navigation, function

The location of the vehicle, as well as the direction and distance to the destination (after entering the destination) are determined with the aid of the navigation system. The data needed to reach the destination (destination-oriented navigation) are calculated in the navigation processor of the COMAND controller unit.

The navigation system is activated by calling up the "NAVI" menu on the COMAND display or by pressing the telephone/navigation quick select button (A40/9s5) on the front central operating unit.

Predictive text input (speller)

While entering a destination, the letters that are still missing are completed from a stored list with the aid of the predictive text input feature. The predictive speller refers to the entry of the destination and the street during destination-oriented navigation. The "Special Destinations" menu is supplemented by the "Bypassing other Locations" and "National Destinations" submenus.

Destination entry

The destination is entered menu-assisted on the front central operating unit and is processed by the navigation processor integrated into the COMAND controller unit. The following options are available for entering the destination:

via destination memory
Destination entry
Special destinations (e.g. railway station, airport etc.)
last destination entry
Entry of intermediate destinations
Entry of address (e.g. zip code, street name, etc.)
Destination via map
Travel guide
Destination memory with individual destinations

Position finding

The navigation processor integrated into the COMAND controller unit calculates the location of the vehicle by constantly comparing the localization results from the following 3 methods:

Basic position finding (dead reckoning)
Global Positioning System (GPS) position finding
Map-based position finding

Route calculation

The route is calculated and then stored in the navigation processor integrated into the COMAND controller unit following destination input or automatically after any deviation from the proposed route.

The calculated route is stored in the navigation processor.

Destination-oriented navigation

Destination-oriented navigation begins once the navigation processor integrated into the COMAND controller unit has calculated the route. 3 types of display can be selected for graphic destination-oriented navigation:

With a map
With a map and symbol display before turning-off points
With a symbol display (sign symbols)

It is possible to change arbitrarily between the 3 types of presentation. In all cases, destination-oriented navigation is supported by voice output the over the speaker system.
