Navigation systems for VW and Audi VW and Audi navigation systems The Audi A8 from model year 1994 onwards was the first vehicle in the Volkswagen Group to be fitted with a navigation system. BAYERN 3 FM1 TP Visual route recommendations are displayed on a dot-matrix monitor in the dash panel insert. Audible route recommendations are played back over a separate loudspeaker. HAUPTSTRASSE SSP 199-002 This system is also fitted in the Passat from model year 1997 onwards.

Basic principles The Global Positioning System The Global Positioning System (GPS) makes satellite navigation possible. The Global Positioning System was originally developed for military purposes by the US Ministry of Defence. For military reasons, the quality of the transmitted satelIite data for position finding is deliberately reduced for civilian use using a special procedure. The military version uses a type of random-number generator that "hashes" the radio signals containing the satellite data.
Global Positioning System (GPS) The Global Positioning System (GPS) currently comprises a total of 24 satellites which are evenly distributed over six orbits at an altitude of approximately 20,000 kilometres. They each circle the earth once every 12 hours. With this arrangement, every point on the earth theoretically has radio contact to at least four satellites.
Basic principles Reception interference of satellite signals Reception interference may occur if the satellite transmitter does not have line-of-sight contact with the receiver of the Radio Navigation System or if the satellite signal is reflected off buildings, mountains, etc.
Dead-reckoning navigation The system components of the Radio Navigation System increase the accuracy of position fixing. The navigation control unit calculates the route profile from the signal supplied by the angle of turn sensor for determining changes in the direction of travel to the left/right and the pulses generated by the ABS wheel speed sensor for calculating the distance travelled. . Dead-reckoning navigation is the result of the interplay between these two sensors.
Basic principles How vehicle navigation works 1. The driver enters the desired destination using the operating and function keys. START 2. The position of the destination is determined using the street map on the CD-ROM. 3. The navigation control unit calculates the current vehicle position accurate to approx. ±100 m using the satellite data it receives. + _ 100m 4.

The angle of turn sensor The angle of turn sensor is located in the housing of the Radio Navigation System. The angle of turn sensor records changes in the direction of travel to the left and right.
Basic principles Function of the angle of turn sensor Rotational axis The angle of turn sensor is shaped like a tuning fork. The two legs of this element are designed as oscillating bodies. When the ignition is turned on, voltage is applied to the lower piezoelements. They then begin to oscillate. The oscillations are transmitted to both limbs.
Cornering When the vehicle is cornering, the upper sections of the legs are bent by the Coriolis force for as long as the vehicle takes to negotiate the corner. A voltage is produced in the upper piezoelements of the angle of turn sensor. The level of this voltage is dependent on the change in direction of travel. When negotiating a corner from left to right, for example, the sign before the voltage changes.
Basic principles ABS wheel speed sensor The wheel speed pulses produced by one of the ABS wheel speed sensors at the rear axle is used for measuring the distance travelled by the vehicle. The navigation control unit receives this data from the ABS control unit. Effect of signal failure The navigation system cannot be started. Self-diagnosis The connection to the ABS control unit is monitored.
Radio loudspeakers Audible route recommendations are played back over the radio loudspeakers. SSP 199-028 Navigation CD-ROM TELE ATLAS 1998 - I The street map and the operating software are stored on the navigation CD-ROM. The CD-ROMs are updated twice a year.

Operation and function Part 2 Operation and function of the VW and Audi Radio Navigation Systems The operation and functions of the VW Radio Navigation System and the Audi Plus Navigation System are described on the following pages. You will also find information about self-diagnosis, test functions and service. For a quick overview of the differences between the two systems, please refer to the chapter on "Differences between the VW and Audi Radio Navigation Systems".
With the new method of operating the Radio Navigation System via function menus, most functions can be executed by using two rotary push-buttons.
