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

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.

Overview
23-279
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 customer concern.
The Comm.Bus connects the HFL and the navigation unit.
If a POI phone number is available, the navigation unit sends the phone number (on the calcurate route to screen) to
the HandsFreeLink control unit for dialing.

23-284 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.
