Function requirements 

- Status "Circuit 30 ON"

- The Auto pilot system (APS) is operating properly

- No fault on global positioning system (GPS) antenna system

- Signals are available from at least 3 GPS satellites.

- Proper communication with ESP control unit (N47-5)

- Destination has been entered

- the route has been calculated.

General 

The position finding and destination-oriented navigation function is divided into the following subareas:

- General information on GPS position finding

- Function sequence for GPS position finding

- General information on basic position finding

- Basic position finding function sequence

- Recalibration

- General information on route calculation

- Function sequence for destination-oriented navigation through voice output

- General information on dynamic route guidance

- Function sequence for dynamic route guidance

Operating instructions 

Operation takes place using the control buttons of the radio and navigation unit (A2/56).

During an active voice output the volume of the announcement can be adjusted by the following components:

- Using the rotary switch on the radio and navigation unit

- With the + and - buttons, for selecting specific functions and volume control (S111s1) in the right multifunction steering wheel button group (S111)

General information on GPS position finding 

The GPS is a satellite-based positioning system. It is available worldwide. The GPS satellites permanently transmit time and position data (longitude and latitude). GPS position finding is irretrievable after vehicle transport (e.g. by train or ferry or after towing). A new GPS position (after interruption of the satellite reception) can take several minutes (up to 20 minutes when the equipment is commissioned).

The accuracy of the position finding and the actual calculation is essentially based on the measurement of the runtimes of the signals transmitted synchronously by the various satellites.

Function sequence for GPS position finding 

The GPS signals are received by the GPS receiver that is integrated into the radio and navigation unit directly from the GPS antenna (A2/93a6).
