The GPS cannot detect the vehicle’s position during the
following conditions: Metallic window tinting above the GPS antenna.
 When only three satellite signals are received (Four satellite signals are required for accurate positioning).
 When driving near high tension power lines.
 When the satellite signals are blocked by the operation of some electronic aftermarket accessories
including, but not limited to non-OEM in-dash
entertainment units (radio, CD players/changers,
radar detectors and theft recovery systems) and cell
phones placed near the navigation system.
 When the satellite control centers are experiencing problems.
The accuracy of the GPS is reduced during these
instances:  Metallic window tinting above the GPS antenna.
 When only three satellite signals are received (Four satellite signals are required for accurate positioning).
 When driving near high tension power lines.
 When the satellite signals are blocked by the operation of some electronic aftermarket accessories
including, but not limited to non-OEM in-dash
entertainment units (radio, CD players/changers,
radar detectors and theft recovery systems) and cell
phones placed near the navigation system.
 When the satellite control centers are experiencing problems. Whenever the navigation system is giving guidance,
the front speakers are muted. When the voice control
system is being used, all of the speakers are muted.
 In cold temperatures, the display may stay dark for the first 2 or 3 minutes until it warms up.
 When the display is too hot because of direct summer sunlight, it will remain dark until the temperature
drops.
 When the humidity is high and the interior temperature is low, the display may appear cloudy.
The display will clear up after some use.
 Fingerprints on the touch panel may sometimes be noticeable because of the panel’s low-reflection
coating. Clean the screen with a soft damp cloth. You
may use a mild cleaner intended for eye glasses or
computer screens. To avoid scratching the panel, do
not rub too hard, or use abrasive cleaners, or shop
towels.
 The touch panel consists of a touch sensitive resistive membrane covering the display. Unlike previous
systems, you must actually touch the display to
activate it. Never use hard or sharp implements to
operate the screen because you risk damaging the
sensing membrane. If a touch switch does not
function immediately, shift your finger slightly, and
touch it again.

Symptom DuplicationService Precautions
System Initialization
23-92 Navigation System
General Troubleshooting Information (cont’d)
 If you can duplicate the symptom, compare it to a
known-good vehicle. Only use a vehicle of the same
model, same year, same trim, and same software
version. If you can duplicate the symptom in the
known-good vehicle, then it is a characteristic of the
system.
 When the symptom can be duplicated, follow the self- diagnostic procedures and the appropriate
troubleshooting procedures.
 When the symptom does not reappear or only reappears intermittently, ask the client about the
conditions when the symptom occurred.
– Try to establish if outside interference may be the cause.
– Try to duplicate the symptom under the same conditions the client experienced.
– Vibration, temperature extremes, and moisture (dew, humidity) are factors that are difficult to
duplicate.
– Inspect the vehicle for aftermarket electronic devices (vehicle locators, radar detector amps, etc.)
that may be hidden.
When troubleshooting navigation system problems,
ensure that the known-good vehicle is the same
software version year and model as the vehicle being
serviced. Mixing incompatible navigation DVDs or
other system components can delay the
troubleshooting process by creating effects unrelated to
the original problem.  If you need to replace the navigation unit, inform the
customer that personal information in the navigation
system may be lost. If possible, have the client record
their personal information before the unit is replaced
On ’07-08 models you can back-up the navigation
data and transfer it to a new navigation unit. See save
users memory (see page 23-150).
 Before disconnecting the battery, make sure you have the anti-theft codes for the audio and the
navigation system, and write down the audio presets.
Also obtain any PGM-FI or transmission DTCs and
freeze frame date (which are lost when the ECM/PCM
loses power).
 When the battery is disconnected, the internal GPS clock is reset to 0:00. The clock will reset to the
correct time after the system finishes GPS
initialization.
 After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take from 10
to 45 minutes.
 Before returning the vehicle to the client, enter the audio and navigation anti-theft security code, then
enter the audio presets.
 Adjust the setup clock settings (time zone and daylight savings) in the navigation system.
If the navigation system loses power (like the battery
was disconnected), the navigation system requires
initialization. Once completed, your system is ready to
use.
This initialization requires the following:  Entering the 4-digit anti-theft security code to unlock the system
 GPS initialization (may not be needed depending of the length of time the system was without power)
 Map matching to align the GPS to a location on the map

The system is acquiring its GPS signal.
This could take up to 10 minutes. Engine must be running
 Vehicle must be parked outside, away from buildings
 Do not move the vehicle at this time
***Wait***
Any time the navigation system loses power, you need
to enter the 4-digit anti-theft code on the navigation
system display. The 4-digit code is located on a small
card that was given to the customer. Enter the 4-digit
code, then select Done.
If the navigation system anti-theft code is missing, use
the interactive Network (iN) to look it up. You will need
the serial number for the navigation unit to do this.
You can view the serial number by entering the
diagnostic mode. Select Unit Check from the main
menu, then the Navi ECU diagnostic screen. This gives
you the serial number without removing the navigation
unit.
The iN may display more than one code for a given
serial number. This is because serial numbers are not
unique. You may have to try more than one 4-digit code.
If no code is shown, or if the code(s) given do not work
in the navigation unit, contact the Automobile Warranty
department. If the code 0000 works, replace the
navigation unit.
When replacing the navigation unit, make sure you give
the customer the new anti-theft security code. NOTE: You must park the vehicle outside with a clear
view of the southern sky.
Depending on the length of time the battery was
disconnected, your system may require GPS
initialization. If it does, the following screen appears:
If this procedure is not necessary, the system proceeds
directly to the Disclaimer screen. During initialization,
the system searches for all available GPS satellites, and
obtains their orbital information. During this procedure
the vehicle should be out in the open with a clear view
of the sky.

troubleshooting while in the shop.
This part of the initialization matches the GPS
coordinates with a road on the map screen. To do this
part of the procedure, make sure that the navigation
system displays a map, and drive the vehicle on a
mapped road shown on the map screen. Do not enter a
destination at this time. When the name of the current
road you are driving on, appears at the bottom of the
screen, the entire procedure is complete. Your system
is now ready to use. If the navigation DVD is lost or damaged, or you need a
yearly
updated DVD, you have 2 ways to purchase one.
You can either call 888-291-4675, or order on-line at
www.hondanavi.com.
Both methods require a credit card. The DVD cannot be
ordered through the parts system. The following DVDs
will not work in this navigation system:
 Earlier model navigation DVDs (black, orange, or older vesions with a white label)
 Map software programs manufactured by other companies
 DVD movies, or DVDs containing audio recordings
 Copies of an original Navigation DVD
Update DVDs are available for purchase usually in the
fall of each year. They may contain the following:  Enhanced maps and points of interest (POI) coverage
 Fixes for minor software bugs
 Additional features
NOTE:  Map matching must be done any time the DVD is removed or replaced.
 Always order navigation DVDs on an as-needed basis. During a typical model year, each color DVD may
undergo a half a dozen software only version
upgrades to fix minor issues on some or all models
the DVD supports. This is normal. Usually only the
letter at the end of the version number changes,
while the database (maps and POIs) remain
unchanged.
 Never promise your customers future free updates.
There are no free programs for updating the
navigation DVD. Update DVDs are generally available
for purchase each fall. The on-time DVD order site
provides information when an update for a particular
color DVD is available, damaged discs are not
warrantable.

Overview
23-101
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 client concern.

23-106 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.
