Before you set off, you study the route on a map or street plan. During the journey, you find your bearings by reading traffic signs and noticing striking features of the landscape. The front passenger may also be helpful. For various reasons, however, he or she may not always be able to help you out. We all know what it means to get lost. Navigation involves locating the position of a vehicle, as well as determining the direction and distance of your destination and taking the necessary steps to reach your destination. Satellite-aided navigation enables you to travel from your starting point to your destination quickly, safely and comfortably without having to read maps.7Basic principlesThe Global Positioning SystemThe 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. The encrypted corrective data which is transmitted in parallel cannot be decoded by civilian GPS receivers. For civilian use, therefore, it is only possible to determine positions accurate to ±100 metres.STARTFINISHSSP 199-0078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.SSP 199-009Position calculation Each time it is switched on, the Radio Navigation System attempts to receive the signals sent by the satellites. Reception from at least three satellites is necessary for an accurate position fixing. Only then can the position of the receiver be calculated at any point on the earth's surface.SSP 199-010Radio trafficThe satellites radio an ID code, their position and a high-precision timing signal earthwards at intervals of one millisecond. The GPS receiver in the Radio Navigation System receives the satellite data and calculates how long the data transmission took by comparing the timing signal with its internal high-precision clock. If the navigation computer receives data from at least three satellites, it is able to calculate the vehicle's position.36 K VKSSP 199/0119Basic principlesReception interference of satellite signalsReception 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. In the following situations, the radio link with the satellite may be interrupted or faulty: In - Street canyons - Valleys - Tunnels - Multi-storey car parks This may lead to an inaccurate position fixing or render the system unable to locate the vehicle.AU DISSP 199-012Although the Global Positioning System is the primary source of information for the Radio Navigation System, the system is able to make allowance for short periods of reception interference. For this purpose, the direction of travel and distance travelled are only calculated using the information provided by the angle of turn sensor and the wheel speed pulses generated by the ABS wheel sensor.Comparison with GPS signals is not possible, and position fixings are less accurate when reception is disturbed. As soon as GPS signals can again be received, the previously calculated position is corrected.10Dead-reckoning navigationThe 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. The navigation control unit compares the route profile with the street map stored on the CDROM several times per second. This comparison process is known as “map matching“. The accuracy of position fixing can thus be increased to ±5m in urban areas and ±50m on long, straight country roads or motorways. If the vehicle is located on a road which is not stored on the CD-ROM, the message “OFFROAD“ appears on the display. “Map matching“ cannot be performed then. Therefore, only the straight line distance and the direction to the destination are displayed.SSP 199-014FM2 5GPSffnTP017 75 km ENTER ruft die Kartendarstellung aufVehicle navigation is the overall result of the interplay between satellite navigation and deadreckoning navigation.Satellite navigationDead-reckoning navigationVehicle navigationSatellite GPS antenna and receiver Navigation control unit+Turn angle sensor ABS wheel sensor CD-ROM Navigation control unit=SSP 199/00811Basic principlesHow vehicle navigation works1. The driver enters the desired destination using the operating and function keys.START2. 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. 4. The vehicle position is determined by dead-reckoning navigation accurate to ± 5m and by comparison with the digital map data stored on the CD-ROM. 5. The navigation control unit calculates the distance, the direction of travel, the change of direction of travel, etc.+ _ 100m+ _ 5m1023 - + = 7 8 9 4 5 6 1 2 36.

The system continuously monitors whether the driver follows the route recommendations. 9. The system tells the driver when he has deviated from the recommended route.!10. If the driver stays on this route, the system recalculates the distance to the destination.11. When you reach your destination, the driver hears the message “You have reached your destination“.FINISH12Notes13Basic principlesSystem componentsControl unit with control panelDISPLAYAudi navigation+FM2 5ffnWESTSTRASSETPZOOM--GPSTPFMNavigationssystem017 75 kmCD Change ControlINFOMODEThe following components are integrated in the control unit with control panel:TIMINFONAVITONE RETURNFM2 1AS AMD-Radio MITTELSTRASSEENTER ruft die Kartendarstellung aufEinschalt TA-Min Telefon Navigation Min GALAÄndernLastNAVIGATIONAUDIORADIO / CDAS SCAN1 2 3ÄndernStumm4 5 6ComponentFunctionLautstärke SetupAbruch mitSSP 199-016Operator buttons and function keys Colour multifunction displayVarious functions can be controlled with the operating and function keys, depending on whether the system is in Radio mode, Audio CD mode or Navigation mode. The colour multifunction display can be adjusted horizontally and vertically. The display can also be switched over to night illumination. This makes the display easier to read at night. The radio is identical to the VW-GAMMA radio or Audi-Concert radio, model year 1999. Radio stations for FM (VHF = very high frequency) and AM (medium wave) can be received. The GPS receiver automatically receives signals from the available GPS satellites via the navigation antenna.RadioGPS receiverCD-ROM driveThe CD-ROM drive plays back navigation CDs. Playback of audio CDs is not possible.Angle of turn sensorAn angle of turn sensor records changes in the direction of travel. It replaces the magnetic field sender previously used.14The angle of turn sensorThe 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. The advantages are: Immunity to magnetic interference Compact size Greater accuracy No calibration requiredNavigatiTIM INFOonssystem CD Chan ge ControlFM2 5GPSffnWESTST RASSETPNAVIAN1 2 3017 75 km ENTER MITTEL STRASS ruft die E Kartend arstellun g auf4 5 6SSP 199-017When the vehicle changes its direction of travel, it rotates about its vertical axis. The angle of turn sensor detects this rotational movement and informs the navigation control unit. The navigation control unit then calculates the angle of the direction change. In order to distinguish between forward and reverse movement, the control unit receives a signal from the reversing light switch. The distance travelled is still required in order to calculate the curve radius. This is determined with the aid of the wheel speed pulses of an ABS wheel speed sensor.SSP 199-01815Basic principlesFunction of the angle of turn sensorRotational axisThe 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.Lower piezoelement Direction of oscillation Direction of oscillationVSSP 199-019Coriolis forceDirection of rotationDirection of oscillationWhen the vehicle changes direction (e.g. when cornering), the so-called Coriolis force acts on the oscillating legs of the sensor. This Coriolis force acts against the direction in which the vehicle is rotating about its vertical axis. The upper parts of the legs, which is already oscillating sideways, bend as a result.Upper piezoelementThe flexure of the legs is transmitted to the upper piezoelements, thereby generating a voltage in the piezoelement. The navigation control unit can calculate the change in direction of travel from the level of this voltage.Direction of oscillationSSP 199-02016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.SSP 199-021SSP 199-022Straight-line travel No Coriolis force occurs when the vehicle is driving in a straight line. The upper parts of the legs are not bent and no voltage is generated in the piezoelements.SSP 199-023SSP 199-024The angle of turn sensor only detects the angle of a single change of direction The vehicle must be moving before a curve radius can be calculated. Only then is the navigation control unit able to calculate the curve radius and perform map matching using the data produced by the angle of turn sensor and the ABS wheel speed sensor.17Basic principlesABS 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.SSP 199-025Switch for reversing lights The navigation control unit obtains a signal from the switch for the tail-lights when reverse gear is engaged. This enables the control unit to distinguish whether the vehicle is moving forwards or backwards. Effect of signal failure The navigation control unit does not recognise when the vehicle is reversing.SSP 199-026Self-diagnosis Fault type: No signalRoof antenna for radio, car phone and navigation system Integrated in the roof antenna (Triplex) are the antennas for radio mode, car phone mode and navigation mode (GPS).

When the remote supply to an antenna is disconnected, TV picture quality must deteriorate noticeably. This facility to connect and disconnect the power supply to each antenna also allows the associated antenna amp to be tested.If picture quality does not deteriorate when the remote power supply to an antenna is disconnected, it is possible that there is an open circuit in the antenna lead or the antenna amp is defective. This can be established by measuring the voltage on the inner conductor of the coaxial cable. If there is no voltage detected, there is an open circuit in the antenna lead.The Workshop Manuals will be updated after technical modifications are made. Please use the vehicle-specific Workshop Manuals as an aid to carrying out the function test .37Operation and functionDifferences between the VW and Audi Radio navigation systemsVWNavigationssystem CD Change ControlAUDIDISPLAYAudi navigationTIM INFO NAVI+FM2 5ffnWESTSTRASSETPFM1 AS 3BAYERN 3299ZOOM--GPSAS SCAN AUDIO139TP4FMALTMÜHLTAL INGOLSTADTINFOMODE1 2 3017 75 km MITTELSTRASSE ENTER ruft die Kartendarstellung auf16N5 630093TONE RETURNASAM5km GPS ..........RADIO / CDNAVIGATIONSSP 199-045SSP 199-046The AUDI system differs from the VW system the following respects:       Front panels differ according to vehicle type.
