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.

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:

How to Identify Navigation DVD Versions,
and How to Inspect A DVD for Damage
23-271
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: Check any official Acura service website for more service information about the navigation DVDs.
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: Client’s may obtain DVDs from sources
outside the normal ordering process. If you
determine this is the case, recommend that your
customer purchase the appropriate DVD from the
Acura Disc Fulfillment 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
Acura Disc Fulfillment Center.
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
23-279
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.

The yaw rate sensor (located in the navigation unit) detects the direction change (angular speed) of the vehicle. The
sensor is an oscillation gyro built into the navigation unit.
The sensor element is shaped like a tuning fork, and it consists of the piezoelectric parts, the metal block, and the
support pin. There are four piezoelectric parts: one to drive the osc
illators, one to monitor and maintain the oscillation
at a regular frequency, and two to detect angular velocity. The two osc illators, which have a 90-degree twist in the
center, are connected at the bottom by the metal block and supported by the support pin. A detection piezoelectric part
is attached to the top of each oscillator. The driving piezoelectric part is attached to the bottom of one oscillator, and
the monitoring piezoelectric part is attached to the bottom of the other oscillator.
The piezoelectric parts have electric/mechanical transfer characteristics. They bend vertically when voltage is applied
to both sides of the parts, and voltage is generated between both sides of the piezoelectric parts when they are bent by
an external force. The oscillation gyro functions by utilizing this characteristic of the piezoelectric parts and Coriolis
force. (Coriolis force deflects moving objects as a result of the earth’s rotation.) In the oscillation gyro, this force
moves the sensor element when angular velocity is applied.
1. The driving piezoelectric part oscillates the oscillator by repeatedly bending and returning when an AC voltage of 6 kHz is applied to the part. The monitoring-side oscillator resonates because it is connected to the driving-side
oscillator by the metal block.
2. The monitoring piezoelectric part bends in proportion to the osc illation and outputs voltage (the monitor signal).
The navigation unit control circuit controls the drive signal to stabilize the monitor signal.
3. When the vehicle is stopped, the detecting piezoelectric parts osc illate right and left with the oscillators, but no
signal is output because the parts are not bent (no angular force).
4. When the vehicle turns to the right, the sensor element moves in a circular motion with the right oscillator bending forward and the left oscillator bending rearward. The am ount of forward/rearward bend varies according
to the angular velocity of the vehicle.
5. The detecting piezoelectric parts output voltage (the yaw rate signal) according to the amount of bend. The amount of vehicle direction change is determined by measuring this voltage.

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.
