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

How to Identify Navigation DVD Versions,
and How to Inspect A DVD for Damage
23-96Navigation System
General Troubleshooting Information (cont’d)
To determine the navigation version on a particular
model, start the engine, then locate the navigation unit.
Open the DVD door, and push the eject button to eject
the DVD. Hold the DVD by the edges, and check for
these items:
 The DVD label color.
 Read the DVD version on the label, and note it on the repair order. The version number is near the bottom
of the label text (for example, ver: 4.23A). You will
need this version number:
– To verify that the DVD version is appropriate for the vehicle. Check any official Honda service website
for more service information.
– Any time you call Tech Line regarding a navigation system issue.
– To answer client inquires concerning update or coverage issue.
NOTE: Clients may obtain DVDs from sources
outside the normal ordering process. If you
determine this is the case, recommend that your
client purchase the appropriate DVD from the
Honda Disc Fulf illment Center (see ORDERING A
DVD).
– Check the underside of the DVD for signs of mishandling. Deep scratches, or random scratches,
light swirl marks, or fingerprints can cause random
lock-ups, reboots, erratic voice response, erratic
positioning errors, and DVD read or format errors.
NOTE: A damaged DVD is not covered under
warranty unless the disc is damaged by the
navigation unit. Damage by the navigation unit
typically appears as circular scratches caused by
something rubbing against the DVD as it spins. The
damage may appear as arcs or complete circles on
the DVD reading surface.
– Verify that the underside of the DVD is silver, and not a copy with a blue color. Copies will not work
properly and can cause other symptoms that mimic
hardware problems.  Incorrectly colored DVDs being put into navigation
vehicles. This causes the system to either display
error messages, or causes system malfunctions that
mimic a hardware problem. This results in the client
leaving with a malfunctioning navigation system.
 The DVD version provided to the client is out-of date or incompatible with a particular model. This
inconveniences your client by delaying the repair, or
by causing additional (and unnecessary) returns to
your dealership.
 The client experiences bugs or other issues that have already been resolved in later versions currently
available at the fulfillment desk.
If the DVD is defective, or has any of the issues
mentioned above, return the vehicle to your client and
recommend that they order the proper DVD from the
Honda Disc Fulf illment Center (see ORDERING A DVD).
NOTE: Navigation DVDs do not come with replacement
navigation units. If you are replacing a navigation unit
because it is defective (following appropriate service
manual troubleshooting), and the DVD does not eject,
order a DVD. See Obtaining a navigation DVD.

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.
