General Operation
Anti-theft Feature
Symptom DiagnosisSelf-Inertial Navigation Limitations
23-90Navigation System
General Troubleshooting Information
Refer to the Navigation System manual for the
navigation system operating procedures.
The navigation system has a coded theft protection
circuit. Be sure you have the client’s anti-theft security
code before;
 Disconnecting the battery
 Disconnecting the navigation unit A (17P) and C (12P) connector
 Removing the No. 23 (10 A) fuse from the under-hood fuse/relay box
After service, reconnect power to the navigation unit,
and turn the ignition switch ON (II). Enter the 4-digit
anti-theft security codes, then select Done.
If the code cannot be found, use the interactive Network
(iN) to look it up. You can view the serial number in one
of the Navi ECU diagnostic screen (see page 23-139).
Alternatively, you can find the serial number from the
navigation unit in the dash.
When replacing the navigation unit, be sure to give the
client the new anti-theft security code.
Certain circumstances and system limitations can result
in occasional vehicle positioning errors. Some clients
may think this indicates a problem with the navigation
system when, in fact, the system is normal. Keep the
following items in mind when interviewing clients
about symptoms of the navigation system. The limitations of the self-inertial portion of the
navigation system (the yaw rate sensor and the vehicle
speed signal) can cause some discrepancies between
the vehicle’s actual position and the indicated vehicle
position (GPS vehicle position).
The following circumstances may cause vehicle
positioning errors:
 Moving the vehicle with the engine stopped and the vehicle stopped, such as by ferry or tow truck, or if
the vehicle is spun on a turn table.
 Tire slippage, changes in tire rolling diameters, and some driving situations may cause discrepancies in
travel distances. Examples of this include:
– Continuous tire slippage on a slippery surface.
– Driving with snow chains mounted.
– Abnormal tire pressure.
– Incorrect tire size.
– Frequent lane changes across a wide highway.
– Continuous driving on a straight or gently curving highway.
 Tolerances in the system and map inaccuracies will sometimes limit how precisely the vehicle position is
indicated. Examples of this include:
– Driving on roads not shown on the map (map matching is not possible).
– Driving on a road that winds in one direction, such as a loop bridge, an interchange, or a spiral parking
garage.
– Driving on a road with a series of sharp hair-pin turns.
– Driving near a gradual highway exit or transition.
– Driving on one of two close parallel roads.
– Making many 90 degree turns.
– The direction to destination icon or the destination icon shown or the map may be up to several
hundred feet away from the actual location.

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.

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.

DVD Handling and CleaningEarliest DVD Version Application for Each
Model
23-95
To avoid damaging or leaving fingerprints on the DVD,
always handle it by the edges and place it in a jewel
case whenever it is outside the navigation unit. Deep
scratches or fingerprints on the back of the DVD can
cause intermittent rebooting or other system errors.
Smudges and fingerprints can be carefully removed
using a mild cleaner and tissues designed to clean
eyeglasses. To clean a DVD, use a clean soft cloth. Very
gently wipe across the DVD from the center to the
outside edge, never in a circular motion.
Do not place stabilizer rings or labels on the DVD. Each navigation system DVD contains a map/POI (point
of interest) database and the navigation system
software for each model that it supports. Inserting an
older DVD can cause problems since it lacks the
software to provide the specific features needed for that
model. Unfortunately, the navigation software does not
detect or warn you that the version is outdated, and it
may even appear to operate.
NOTE: Replacing a DVD just because the version
number is higher is not always warranted. A higher
software version does not necessarily mean it contains
newer software for your model. The DVD contains
software for all models that use the same color DVD,
and a revised number may or may not have software
fixes or upgrades for the model in question.
Typical warning symptoms that an outdated DVD is
being used include:
 The Acura model navigation screen displayd a Honda logo while booting up.
 A newly introduced model future or accessory may not display properly, and Extension displays instead.
NOTE: Extension may be displayed when using
Music Link, but should never be displayed when XM
is selected.
 The current street (the street being driven on) does not appear properly at the bottom of the map screen
display when the vehicle is driven on a main road.
NOTE: If necessary, compare the operation to the
navigation system of the same model and year
vehicle that has a current DVD.

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.

How to Answer Client Questions About
Navigation CoveragePrecaution on Client Sneak Previews
Is my address covered by the navigation system?
Is my city covered by the navigation system?
The gas station on my corner is now a restaurant. Why
is it still incorrect in the navigation system?
FAQsWhy are some features different or missing compared
to my previous Honda vehicle?
23-97
Some clients may ask questions regarding a city,
address or POI (point of interest) covered by the
navigation system. It is better to verify a coverage
question on an actual vehicle than to disappoint your
client by promising coverage that may be incomplete or
missing in their area. The following suggestions can be
used to answer coverage inquiries from your client.
Using a current production vehicle (of the same model),
enter the client’s address (street first) to see if their area
is covered. Always enter the street first, because
sometimes their city may be included in a neighboring
township, or under some lager metropolitan city name.
If the address is shown in a later year vehicle, but not
your client’s vehicle, you might want to recommend
that your client purchase an update.
For general questions about whether a city is covered,
view the map coverage link on the DVD order site. On
the site, you enter a year and model, and then click on
the Coverage link. You then select a state or province,
and the cities are listed. Of course, this does not
guarantee that the client’s road or address is in the
system. Verifying on an actual production vehicle is
always the best guarantee that your information is
accurate.
For POI-related client questions, explain that
businesses are constantly moving, and there can be a
considerable lag in updating the m
illions of POIs in the
system. The database is updated annually, and the best
way to the verify whether the POI is accurate is verify
the inquiry on a current production vehicle.
Answers to these and other questions regarding
coverage can be found in these locations:
 In the Frequently Asked Questions section of the navigation system manual.
 At the on-line DVD order site, by clicking on the link (see ORDERING A DVD). Your client might request a look (or sneak preview) at
features in the latest navigation software. You should
never preview a navigation DVD in a client vehicle.
Inserting a newer DVD installs the latest software from
the DVD into the memory of the client’s navigation
system. When the original DVD is reinstalled, the newer
software remains in memory and is often incompatible
with the client’s original DVD Map and POI database, or
software.
If wishes to see the latest navigation coverage or
software features, demonstrate it on an in-stock vehicle
that already has the latest DVD version.
If, by chance, a newer version is loaded accidentally,
either by the dealer or the client, the only remedy is to
enter the navigation diagnostic mode’s Version screen
and do a forced download. Check any official Honda
service website for more information about what
patches may need reinstalling.
Hardware and software continually go through updates
and improvements. Features may change or disappear
over time based on the navigation system development.
