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

MODEL 211.0/2 as of 1.6.06 with CODE (525) MB Audio 50 APS radio 

With the aid of the radio control panel and navigation unit (A2/56), the position of the vehicle, the direction and the distance to the destination (after entering the destination) are determined by the integrated navigation processor. Then the required measures for reaching the destination are started (destination-oriented navigation).

Once the navigation system has been activated by opening the driver door (in the background), it is operational via the radio control panel and navigation unit immediately after initialization.

Entry aid (speller) 

While entering the destination using the speller, the letters still to be completed are added from a stored list.

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 via the radio control panel and navigation unit and is processed by the navigation processor. The user can enter the destination in navigation mode in the radio control panel and navigation unit in the following ways:

• via destination memory
• Destination entry
• Special destinations (e.g. hospital, car park, gas station)
• last destination entry
• Entry of intermediate destinations
• Address entry
• Destination via map
• Travel guide
• Destination memory with individual destinations

Position finding 

The radio control panel and navigation unit continuously calculates the position of the vehicle using 3 methods:

These are:

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

The navigation processor calculates the most probable position by continuously comparing the results returned by these 3 methods.

Route calculation 

The route is calculated by the navigation processor in accordance with the specified destination, or automatically, after a deviation from the suggested route has taken place. With the dynamic destination-oriented navigation system, the route calculation is influenced by incorporating traffic information via an external provider by means of radio (TMC). The calculated route is stored in the navigation processor.

Destination-oriented navigation starts once the navigation processor has carried out the route calculation

3 types of display can be selected for graphic destination-oriented navigation:

• Map
• Map and symbol presentation of the turn-off points
• Symbol presentation (system of navigation symbols)

The following display functions are supported:

• Destination-oriented navigation map
• positioning map
• destination map
• Route map
• auto zoom
• Intersection zoom
• traffic jam map
• parking place map

It is possible to change arbitrarily between the types of presentation. In all instances the destination-oriented navigation is backed up by voice outputs over the vehicle speakers.

If the drive is not used for navigation, it is also possible to play audio CDs.

Voice output 

Voice output is conducted:

• As turn-off recommendations
• When starting destination-oriented navigation
• On arriving at the destination

Voice control system 

Voice control can take place by means of letters or complete word input. Destination-oriented navigation starts once the navigation processor has carried out the route calculation
