10. Turn the ignition switch to LOCK (0).
11. Start the engine in the known-good vehicle, and
then do steps 4 thru 10 on the known-good vehicle.
12. Compare the number of stations received in steps 6 and 9 in the client’s vehicle with the number of
stations received in the known-good vehicle.
 If the number of stations received is the same, or within 10 %, the audio unit’s tuner performance
is OK. The problem may be atmospheric
conditions, multi path interference, or other
obstructions to the radio signal.
 If the customer’s vehicle receives fewer stations by at least 10 %, go to step 2 of poor AM or FM
radio reception of interference, with navigation
(see page 23-196), wit hout navigation (see page
23-199). SRS components are located in this area. Review the
SRS component location (see page 24-11).
Also review the precautions and procedures (see page
24-13) in the SRS section before doing repairs or
service.
NOTE:
 Put on gloves to protect your hands.
 Take care not to scratch the dashboard and related parts.
 Lay a workshop towel under the parts when working on them to protect the face panel from scratches or
other damage.
 Do not work in a dusty or dirty place.
 Discharge static electricity from your body before and during the work.
 Do not touch the circuit board(s) with your bare hands.
 Do not work with dirty hands.
 Be careful not to fold the flat plate cable.
 Do not touch the terminal connector of the flat plate cable with your bare hands (If you have touched it,
wipe it off thoroughly.).
 Eject all the discs before removing the audio unit to prevent damaging the CD/DVD player’s load
mechanism.

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.

NOTE: The system cannot complete a full diagnosis unless the engine is running.
 DTC 2703 can be stored when the ignition switch is at ACCESSORY (I). With the ignition switch is
in ACCESSORY (I), the climate control unit is
turned off and the navigation unit loses
communication and stores DTCs. Therefore,
there is a possibility that the system is normal
even DTC 2703 is stored. Check system links with
the engine running, and if it shows normal, the
system is OK at this time.
