NOTE: All items may not apply to this vehicle. See the owner’s manual for more information.
Active noise cancellation The active noise cancellation system cancels some of the vehicle noise. This occurs in the 1,500 2,400 rpm range. Microphones detect the low frequency
sound, and the system outputs a canceling sound from the audio speaker.
AM (Amplitude Modulation)
Amplifier A device that increases the level of a signal by increasing the current or voltage.
Antenna A device used to send or receive electromagnetic waves thr ough the air.
ATA (PC Card) A type of card that has been tested for use in playing WMA, and MP3 music files in the PC Card slot. Sizes of up to 1 GB have been tested.
Audio remote switch The switches on the steering wheel that control the audio system.
Auxiliary jack Allows the customer to use a portable audio device to i nput audio recordings.
Balance A control that changes the relative volume of the left and right channels.
Band A range of frequencies between two definite limits. Bands are assigned by the Federal Communications Commission for specific uses.
Bass An adjustment for the low frequency sounds of around 160 Hz and below.
Byte A unit of storage for computer files and memory. A CD holds approximately 700 million bytes.
Cassette Audio or video magnetic tape container having two reels. Customers can insert it for play back
Compactflash Astandardforsmall-size(3x4cm),memorycardsusedinmobilecomputers, PDAs, digital cameras. Compact flash memory cards are available in size of
32 MB up to 4 GB or more and can be played in the audio PC slot. Sizes above
1 GB have not been tested.
CD (Compact Disc) A 4.5-inch plastic disc containing digital audio recording that is played optically on a laser equipped player. Never use discs with a paper label. In a hot vehicle,
labels can curl up and jam the unit.
CD (audio disc) changer CD player that can store and play more than one CD. Two types are available. Some units accept CDs fed into the changer one at a time, and others accept a
magazine (with CDs stacked in a container).
CD player A com ponent designed to play compact disc recordings using a laser optical
pickup. The signal from a CD player usually requires amplification.
Decibels (db)
Distortion Inexact repr oduction of an audio signal caused by playing music at levels the
audio system cannot handle.
Dolby (noise reduction) A processing system developed by Dolby Laboratories that reduces the background noise on recording media. The result is a cleaner playback from the
audio system.

Some vehicles can play DVD and DVD-A formats.
Equalizer A device that changes the relative volume of individual frequency bands to suit personal tastes of the listener.
Fader The control that adjusts the relative volume levels of front and rear speakers in a four-speaker system.
Format To prepare a PC Card to receive files this function is done on a PC. Always choose either FAT or FAT32, as the NTFS format is not accepted by the system.
Pick the default sectors for the format method selected.
FM (Frequency Modulation) The form of modulation used for radio and television sound transmission in most of the world. Less prone to interference than AM. The FM broadcast band
in North America covers roughly 87.7 to 107.9 MHz.
(cont’d)
The type of transmission used in the standard radio broadcast band from 530 to 1710 kHz.
A method of measuring sound or radio signal strength received by the audio unit antenna.

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.

This screen is for factory use only, and should always
be set to OFF. Occasionally the DEMO setting is turned
ON when vehicles are being used at Auto Shows or
similar events. Turning this feature on, allows the
navigation system to automatically follow a route to a
destination when the vehicle is stationary. The Speed
changes the speed of the demo mode. This diagnostic allows you to independently test the
microphone and the navigation TALK and BACK
buttons. They are used to activate the voice control
system. The microphone is located near the map light
in the roof console. It is directional, and works only with
the voice coming from the driver’s seat.
 Press the navigation TALK button on the steering wheel, wait unit you hear a beep, and in a normal
voice say ‘‘testing’’. The TALK indicator on the screen
should momentarily turn green, and the text Now
Recording... should appear in yellow. If the talk
indicator shown on the screen does not briefly turn
green, check the wiring from the steering wheel
navigation TALK button to the navigation unit. If there
is no Mic Level movement when you speak, then you
should check the wires running from the microphone
in the roof console to the HandsFreeLink control unit
and the navigation unit. If the wires are OK, the
microphone must be faulty; replace the microphone
located in roof console (see page 23-358).
 PressthenavigationBACKbuttononthesteering wheel. This should cause the Cancel indicator on the
screen to momentarily turn green. If it does not
briefly turn green, check the wiring from the steering
wheel navigation BACK button to the navigation unit.
