Overview
23-279
System Description
The navigation system is a highly sophisticated, hybrid locating system.
The navigation unit uses global positioning system (GPS) satellite signals, internal yaw and vehicle speed inputs, and
a map database to show where the vehicle is and to help guide you to a desired destination.
The navigation unit’s GPS receiver receives signals from the GPS, a network of 24 satellites in orbit ar ound the earth.
By receiving signals from several of these satellites, the navigation system can determine the latitude, l ongitude, and
elevation of the vehicle.
Signals from the system’s yaw rate sensor (inside the navigation unit) detects turns, and the ECM/PCM vehicle speed
pulse (VSP) and reverse signal enable the system to keep track of the vehicle’s speed and direction of travel. The
advantage of this hybrid system is that the system can track your position if either the GPS signal or the vehicle speed
signal is missing. For instance, when in a tunnel (no GPS), the speed signal is used to update your position on the map.
Alternately, while the vehicle is being transported on a ferry, GPS signals can show the vehicle position on the map as
it crosses the water.
The navigation system uses the location, direction, and speed information to display the appropriate map and
calculate a route to the destination entered. As you drive to a destination, the system provides both visual and audio
guidance. Audio guidance is sent to the audio unit, and an RGB graphics color signal is sent to the navigation display.
This navigation system also has voice recognition that allows voice control of most of the navigation, and audio
functions. The voice control switches (navigation TALK and navigation BACK buttons on the steering wheel) activate
the voice control system. The microphone on the ce iling receives your voice commands. For more information on this
feature, consult the navigation owner’s guide.
The illumination signal is used by the navigation unit to automatically switch the display mode between the Night and
Day display modes. When the headlights are on, the dash brightness control setting full brightness overrides the Night
display mode, and allows a daytime navigation display with the lights on.
When the navigation system is giving voice guidance commands, the front speakers are muted. When the voice
control system is being used (navigation TALK button pressed), all of the speakers are muted.
The internal GA-Net II bus passes information back and forth between the navigation display, the navigation unit, and
the audio system components. The information passed on this bus are touch button commands, audio muting signal,
audio (radio and XM), and any open in these bus lines can affect the navigation system or other audio accessory
operation.
The clock on the navigation display is set and maintained by the navigation unit. The time is automatically adjusted for
daylight savings, and time zone changes while driving. The time can be adjusted in setup.
Additional information is available about the navigation components following the System Diagram. A glossary of
terms that are used throughout this section follows the detailed information.
The Navigation System Manual in the glove box covers all of the system functions and settings. Use this as a resource
when evaluating a customer concern.
The Comm.Bus connects the HFL and the navigation unit.
If a POI phone number is available, the navigation unit sends the phone number (on the calcurate route to screen) to
the HandsFreeLink control unit for dialing.

23-284 Navigation System
System Description (cont’d)
The global positioning system (GPS) enables the navigation system to determine the current position of the vehicle by
using the signals transmitted from the satellites in orbit around the earth. The sate
llites transmit the satellite
identification signal, orbit information, transmission time signal, and other information. When the GPS receiver
receives a signal from four or more satellites simultaneously, it calculates the current position of the vehicle based on
the distance to each satellite and the satellite’s positions in its respective orbit.
The precision of the GPS varies according to the number of satellites from which signals are received and the view of
the sky. The accuracy is indicated by the color and shape of the GPS icon shown on the display.
No GPS icon None Faulty reception The GPS can’t be utilized due to a faulty GPS receiver, open in the wire, or other
fault or interference.
White GPS icon 2 or less Impossible to detect vehicle positionGPS function is normal. The satellite
signals received by the GPS are too few to
detect the vehicle position.
Green GPS icon 3 Vehicle position detectable in 2 dimensionsThe longitude and latitude of the vehicle
position can be detected. (Less precise
than detection in three dimensions)
4 or more Vehicle position detectable in 3 dimensions (elevation
displayed) The longitude, latitude and the altitude of
the vehicle position can be detected. (More
precise than detection in two dimensions)
The GPS antenna amplifies and transmits the signals received from the satellites to the GPS receiver.
The GPS receiver is built into the navigation unit. It calculates the vehicle position by receiving the signal from the GPS
antenna. The current time vehicle position and signal reception condition is transmitted from the GPS receiver to the
navigation unit to adjust vehicle position.

The navigation unit calculates the vehicle position and guides you to the destination. The unit performs map matching
correction, GPS correction, and distance tuning. It also controls the menu functions and the DVD-ROM drive, and
interprets voice commands. With control of all these items, the navigation unit makes the navigation picture signal,
then it transmits the signal to the navigation display and audio driving instructions to the audio unit.
The navigation unit calculates the vehicle position (the driving direction and the current position) by receiving the
directional change signals from the yaw rate sensor and the travel distance signals from the PCMs vehicle speed pulse
(VSP) signal.
The map matching tuning is accomplished by indicating the vehicle position on the roads on the map. The map data
transmitted from the DVD-ROM is checked against the vehicle position data, and the vehicle position is indicated on
the nearest road. Map matching tuning does not occur when the vehicle travels on a road not shown on the map, or
when the vehicle position is far away from a road on the map.
The GPS tuning is accomplished by indicating the vehicle position as the GPS’s vehicle position. The navigation unit
compares its calculated vehicle position data with the GPS vehicle position data. If there is large difference between
the two, the indicated vehicle position is adjusted to the GPS vehicle position.
The distance tuning reduces the difference between the travel distance signal from the VSP and the distance data on
the map. The navigation unit compares its calculated vehicle position data with the GPS vehicle position data. The
navigation unit then decreases the tuning value when the vehicle position is always ahead of the GPS vehicle position,
and it increases the tuning value when the vehicle position is always behind the GPS vehicle position.
The navigation unit can calculate different routes to a selected destination. You have five options:
 Direct Route Calculate a route that is the most direct.
 Easy Route Calculate a route that minimizes the number of turns needed.
 Minimize Freeways Calculate a route that avoids freeway travel. If that is not possible, keep the am ount of
freeway travel to a minimum.
 Minimize Toll Roads Calculate a route that avoids, or minimizes travel on toll roads.
 Maximize Freeways Calculate a route that uses freeways as much as possible.
The navigation unit transmits audio driving instructions before entering an intersection or passing a junction.
The audio instructions come through the audio unit to the front speakers.
NOTE: The front speakers are muted whenever the navigation system is giving guidance commands, and all of the
speakers are muted when the voice control system is being used.
The map data (including all scale rates) is stored in the DVD-ROM. The map data includes:  Road distances, road widths, speed limits, traffic regulations, passing time at junction, distances to junctions, and the driving instructions for audio guidance.
 Latitude and longitude GPS.
