GLOBAL POSITIONING SYSTEM (GPS) LIMITATIONS

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 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 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.

The accuracy of GPS is reduced during these instances:



Metallic window tinting above the GPS antenna



When only three satellite signals can be received (Four satellite signals are required for accurate
positioning).



When the satellite control centers are experiencing problems.



When driving near high tension power lines.



MUTING LOGIC

Whenever the navigation system is giving guidance, all of the 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.

LCD UNIT LIMITATIONS



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 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.

SYMPTOM DUPLICATION



When the symptom can be duplicated, verify that it is not a characteristic of the system. Review the
navigation 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.



Try to establish possible user error or 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.

SERVICE PRECAUTIONS



If the navigation unit needs to be replaced, inform the client that personal information in the
navigation system will be lost. If possible, have the client record their personal information before the
unit is replaced.



On '07 and later models you can back-up the navigation data and transfer it to a new navigation unit.
See save USERS MEMORY , audio system and navigation system.



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 data (which will be lost when the 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.

Verify map matching.



Before returning the vehicle, enter the audio system and navigation system anti-theft security code,
then enter the audio presets.

NOTE:

When interchanging navigation DVD/parts during diagnosis.
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 causing side effects unrelated to the
original problem.

Adjust the setup clock settings (time zone and daylight savings) in the navigation system.

SYSTEM INITIALIZATION

If for any reason, you lose power to the navigation system (like the battery was disconnected), the
navigation system will require initialization. Once completed, your system will be 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

ENTERING SECURITY CODE

Any time power is disconnected from the navigation unit, the 4-digit anti-theft code must be entered on the
navigation system display. This 4-digit code can be found on a small code card that was given to the client.
Enter the 4-digit code, then select "Done".

If the navigation system anti-theft code cannot found, 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 allows
you to get the serial number without removing the navigation unit.

The N 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, then
replace the navigation unit.

When replacing the navigation unit or audio unit, be sure to give the client the new anti-theft security code.

GPS INITIALIZATION

Depending on the length of time the battery was disconnected, your system may require GPS initialization.
If it does, the following screen appears:

***Wait***

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

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.

Navigation system is unable acquire a proper GPS signal.



Move vehicle to another location



Turn the ignition switch off



Disconnect the battery for 30 minutes to clear the GPS receiver's memory



Reconnect the battery and follow the screen prompts

If this is displayed, turn off the engine, then restart the vehicle. If you now see the Disclaimer screen, the
GPS initialization is complete.

MAP MATCHING

This part of the initialization matches the GPS coordinates with a road on the map screen. To perform this
part of the procedure, ensure that the navigation system is displaying 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.

OBTAINING A NAVIGATION DVD

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) 549-3798, or order on-line at www.acura.com.

Both methods require a credit card. The DVD for this model has a white label, and cannot be ordered
through the parts system. The following DVDs will not work in this navigation system:



Earlier model navigation DVDs (black 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:



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 .

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
