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.

Sensor element top view
The yaw rate sensor (located in the navigation unit) detects the direction change (angular speed) of the vehicle. The
sensor is an oscillation gyro built into the navigation unit.
The sensor element is shaped like a tuning fork, and it consists of the piezoelectric parts, the metal block, and the
support pin. There are four piezoelectric parts: one to drive the osc
illators, one to monitor and maintain the oscillation
at a regular frequency, and two to detect angular velocity. The two osc illators, which have a 90-degree twist in the
center, are connected at the bottom by the metal block and supported by the support pin. A detection piezoelectric part
is attached to the top of each oscillator. The driving piezoelectric part is attached to the bottom of one oscillator, and
the monitoring piezoelectric part is attached to the bottom of the other oscillator.
The piezoelectric parts have electric/mechanical transfer characteristics. They bend vertically when voltage is applied
to both sides of the parts, and voltage is generated between both sides of the piezoelectric parts when they are bent by
an external force. The oscillation gyro functions by utilizing this characteristic of the piezoelectric parts and Coriolis
force. (Coriolis force deflects moving objects as a result of the earth’s rotation.) In the oscillation gyro, this force
moves the sensor element when angular velocity is applied.
1. The driving piezoelectric part oscillates the oscillator by repeatedly bending and returning when an AC voltage of 6 kHz is applied to the part. The monitoring-side oscillator resonates because it is connected to the driving-side
oscillator by the metal block.
2. The monitoring piezoelectric part bends in proportion to the osc illation and outputs voltage (the monitor signal).
The navigation unit control circuit controls the drive signal to stabilize the monitor signal.
3. When the vehicle is stopped, the detecting piezoelectric parts osc illate right and left with the oscillators, but no
signal is output because the parts are not bent (no angular force).
4. When the vehicle turns to the right, the sensor element moves in a circular motion with the right oscillator bending forward and the left oscillator bending rearward. The am ount of forward/rearward bend varies according
to the angular velocity of the vehicle.
5. The detecting piezoelectric parts output voltage (the yaw rate signal) according to the amount of bend. The amount of vehicle direction change is determined by measuring this voltage.

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.

23-298Navigation System
System Diagnostic Mode (cont’d)
The System Links function runs automatically and
displays a flashing message at the bottom of the
screen reminding you to have the engine running
for the test. The diagnostic tests the following:
 Most of the wires connecting the navigation components shown in the block diagram.
 The results from the various components shown in the block diagram.
 The microphone is tested by listening to the bong sound produced by the navigation unit from the
speakers when the diagnostic is started. This
requires that the audio system be operating
normally.
When the diagnostic finishes, the icons turn
different colors based on their test status. The color
definitions are shown below and can also be seen
by selecting Help on the System Links screen.
The indication on the screen may not change until
you exit and reenter the Self-Diagnosis mode. In
some cases, you may have to restart the engine for
the indication to change. After you repair the
affected component or harness, repeat this
diagnostic. Explanation of each icon
Each icon color is explained in the table below.
Green The system ran a diagnosis and the results are OK.
Red Errors that require replacement of hardware or harness. Examples
are connection error or memory
diagnosis errors. Troubleshooting
for DTCs.
Yellow Errors that doesn’t require hardware replacement, such as an
open display cover, an incorrect
DVD, leaving the vehicle in
ACCESSORY (I), or because of a
missing accessory, like the
rearview camera.
White The diagnosis is running. The screen functions are locked out
while the diagnosis is runs.
Gray The system cannot automatically check this function. You have to
select the diagnosis item and
manually do additional testing,
like checking the navigation
buttons in the Hard Key test.
When you complete the Hard Key
test and return to the System
Links menu, the gray icon turns
green.
NOTE: By selecting the HELP icon, you can see a
description for each color.

This screen shows the current status of GPS reception.
The circular diagram shows the current location of the
GPS satellites (yellow numbers) as they would appear
in the sky. The outer circle represents the horizon
(0 degrees elevation). The middle and inner circles
represents 30 and 60 degrees respectively. The very
center of the diagram (90 degrees elevation) is directly
overhead. Nearby obstructions, like tall buildings will
block satellites in that direction. That is why it is
necessary to be in an open area to effectively
troubleshoot GPS reception issues. The sate llite
numbers shown on the diagram correspond to the PRN
number in the GPS Details screen. There are always at
least 24 active GPS satellites in orbit. Because satellites
fail, and have to be removed from service, spares are
always parked in orbit, ready to be activated. This is
why the PRN (satellite ID number) can be greater than
24.
NOTE: When you use this screen for troubleshooting,
park the vehicle outside, away from buildings, tall trees,
and high-tension wires for at least 10 minutes with the
engine running.  The Number of Satellites box shows the number of
acquired satellites (maximum of 12). It should contain
three or more icons. If not troubleshoot for GPS icon
is white or not shown (see page 23-341).
 The Current Position shows latitude, longitude, and elevation (in feet). If there are less than four satellites,
the elevation can be grossly inaccurate.
 The Date/Time field shows the current date, and also a time that includes daylight savings and other
offsets entered by the customer in Setup screen 2
Adjust Time Zone/Clock.
NOTE: Pressing the map/guide button displays the
satellite number on each circle.
