Audio System
Sound Quality Diagnosis (cont’d)
Diagnostics CD 07AAZ-SDBA100
Do this test to check for electrical noise being induced
into the audio system.
NOTE: Electrical noise may be caused by outside
sources that cannot be handled by the audio system.
Make sure you remove any cell phones and/or turn off
any aftermarket device before beginning this test.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 4 (digital zero) at a normal, or slightly higher than normal, volume level.
3. Operate any electrical device that may create electrical noise in the audio system, including
starting the engine.
4. Play track No. 5 (near digital zero) at a normal, or slightly higher than normal, volume level.
5. Operate any electrical device that may create electrical noise in the audio system, including
starting the engine.
6. Play track No. 6 (SNR) at a normal, or slightly higher than normal, volume level. 7. Operate any electrical device that may create
electrical noise in the audio system, including
starting the engine.
 If no abnormal noise is heard, go to individual speaker test.
 If the noise is present only during the SNR track, replace the navigation unit or audio unit.
 If the noise is heard during the digital zero or near digital zero track, check for;
– Poor ground for the audio unit, amplifier, engine or battery cable
– Pinched or shorted speaker or amplifier wire
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit
– Other faulty components causing excessive electrical noise (ignition coils, alternator, door
lock actuators, etc.). Disconnect any suspect
components, and then replay the tracks that
were originally noisy. If the noise is gone,
check the component’s circuit and the
component.

Sound Quality Diagnosis (cont’d)
Diagnostics CD 07AAZ-SDBA100
Do this test to find rattles or reverberation that may
cause a perception of poor sound quality.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 13 (sweep from 500 Hz to 35 Hz) at a normal, or slightly higher than normal, volume
level.
3. Listen to each speaker for poor sound quality or reverberations caused by specific frequencies. Use
the voice-over to estimate the frequency that
causes the vibration. Use the audio unit’s fader and
balance settings to help isolate the channel with the
problem.
 If vibrations or poor sound quality are heard, go to step 4.
 If no vibrations or poor sound quality are heard, go to sound judging.
4. Choose the appropriate track from No. 14 to 25 (small range frequency sweep) or 26 to 53 (single
frequencies) to recreate the frequency that caused
the poor sound quality or vibration located in step
3: this aids in diagnosis of the cause.
NOTE: When you get to the track that recreates the
problem, select the repeat function on the
navigation unit or audio unit, this will help you
isolate the cause.
5. Replace or insulate the source of the vibrations or, if the speaker is the source of the poor sound
quality, replace it. Diagnostics CD 07AAZ-SDBA100
 Do this test to compare overall sound quality, imaging, and dynamics between the client’s vehicle
and a known-good vehicle. Only use a vehicle of the
same model and trim level for this test.
 Make sure the vehicle is using only OEM speakers.
1. In the client’s vehicle, set the bass, treble, fader, and balance settings to the client’s normal settings
that were written down before beginning testing.
2. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
3. Play tracks No. 7 to 12 (sound quality, midland, dynamics, and imaging demonstration tracks) at a
normal, or slightly higher than normal, volume
level. Write down the volume setting being used.
4. Listen to areas of the track that stand out as being either very clear, or poorer than other areas of the
track.
5. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit of a known-
good vehicle.
6. Play the tracks at the same volume level and the same bass, treble, balance, and fader settings as
used in step 3 in the client’s vehicle.
7. Listen to the same area of the track that stood out as being either very clear or poorer than other
areas of the track.

23-266Navigation System
General Troubleshooting Information
Refer to the navigation system manual for the
navigation system operating procedures.
The navigation system and audio unit have a coded
theft protection circuit. Make sure you have the anti-
theft security code before:
 Disconnecting the battery.
 Disconnecting the navigation unit connector A (24P) and C (8P).
 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 to ON (II). Enter the 4-digit
anti-theft security code, 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 ECU Info diagnostic screens (see page 23-305).
Alternatively, you can find the serial number on the
underside label which is located on the navigation unit
in the trunk.
When replacing the navigation unit, be sure to give the
customer the new anti-theft security code.
Certain circumstances and system limitations will result
in occasional vehicle positioning errors. Some client’s
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 client’s
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 discrepancies between the
vehicle’s actual position and the indicated vehicle’s
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
– Very bumpy roads
 Tolerances in the system and map inaccuracies sometimes limit how precisely the vehicle’s 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 GPS cannot detect the vehicle’s position or
elevation during the following instances:  For the first 5 to 10 minutes after reconnecting the battery (this process can take as long as 45 minutes).
 When the satellite signals are blocked by tall buildings, mountains, tunnels, large trees, inside
parking structures or large trucks.
 When the GPS antenna is blocked by metallic window tinting or by an object placed above it in the
vehicle. The GPS antenna requires a clear
unobstructed view of the sky.
 When there is no satellite signal output (signal output is sometimes stopped for sate llite servicing).
 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.

Muting Logic
LCD Unit LimitationsSymptom Duplication
23-267
The accuracy of the GPS is reduced during these
instances:
 Metallic window tinting above the GPS antenna.
 When only three or less satellite signals are received (Four satellite signals are required for accurate
positioning).
 When driving near high tension power lines.
 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. If
the HandsFreeLink is in use, the voice control system is
unavailable and a message appears onscreen.
NOTE: The screen is not touch sensitive. Use the
interface dial and buttons to select items on the screen.  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 (you may see an error message displayed
stating this fact).
 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 screen may be noticeable. 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.  When the symptom can be duplicated, verify that it is
not a characteristic of the system. Review the
navigation system manual and compare it to a
known-good vehicle (with the same software and
database), under the same conditions. If the
symptom is not the same as the known-good vehicle,
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.
– Always ask the client to demonstrate the problem.
– Trytoestablishpossibleusererrorora misunderstanding of the system.
– Try to establish if outside interference may have been 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 after-market electronic devices (vehicle locators, amps, radar detectors,
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 symptoms or
issues causing effects unrelated to the original problem.

the vehicle, see your dealer.
 If you need to replace the navigation unit, you can
back-up the navigation data and transfer it to a new
navigation unit. See Save users memory (see page
23-310).
 When the battery is disconnected, the internal GPS clock resets to 0:00. The clock resets to the correct
time after the system finishes GPS initialization.
 Before disconnecting the battery, make sure you have the anti-theft codes for the audio system 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).
 After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take from 10
to 45 minutes.
 Adjust the setup clock settings (time zone and daylight savings) in the navigation system.
 Before returning the vehicle to the client, enter the anti-theft codes for the audio system and 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 Any time the navigation system loses power, you need
to enter the 4-digit anti-theft code on the navigation
system display. This 4-digit code is located on a small
code 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 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 ECU info diagnostic screen. This allows
you to get 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 or audio unit, make
sure you give the client 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:

procedure. If the problem persists, see your dealer.
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.
If the navigation system finds the satellites properly,
this box clears, and changes to the Disclaimer screen. If
within 10 minutes the system fails to locate a sufficient
number of satellites to locate your position, the
following screen appears.
It this screen appears, turn off the engine, then restart
the vehicle and move it to a different location. If the
disclaimer screen appears, the GPS initialization is
complete.
NOTE:
 The average acquiring time is less than 10 minutes, but it can take as long as 45 minutes.
 If the system is still unable to acquire a signal, follow the instructions on the screen. If this screen appears
again, go to troubleshooting for the GPS icon is white
or not shown (see page 23-341).
 Skip to a CSF screen by pushing the MENU and INFO buttons at the same time and can move to an System
Links screen.
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 is 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 two ways to purchase
one. You can either call 888-549-3798, or order on-line
at www.acura.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, light blue label and the older versions with a white label)
 Map software programs manufactured by other companies
 DVD movies, or DVDs containing audio recordings
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 customer future free updates.
There are no free programs for updating the
navigation DVD. Update DVDs are generally available
for purchase each fall. The online DVD order site
provides information when an update for a particular
color DVD is available.
 Damaged discs are not covered by warranty unless they have been damaged by the navigation system.

DVD Handling and CleaningEarliest DVD Version Application for Each
Model
23-270 Navigation System
General Troubleshooting Information (cont’d)
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 may display a Honda logo while booting up.
 A newly introduced model feature or current accessory may not display properly, and Extension
will display 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.
