NOTE: Check the vehicle battery condition first.
 Make sure that the correct DVD color and version are installed.
 Check any official Honda service website for more service information about the navigation system.
 Check the connector for poor connection or loose terminals.
 Before troubleshooting, make sure you have the navigation system 4-digit anti-theft code.
 After troubleshooting, enter the navigation system anti-theft code.
Before assuming that a voice complaint is hardware
related, ensure that the voice control system is being
operated correctly.  Make sure you are on the correct screen when trying to issue a voice command. For instance, the
command ‘‘Find the nearest Italian Restaurant’’ only
works on a Map screen (See the Navigation System
Manual for a complete list of allowed voice
commands for the information being displayed.).
 Close the windows, moonroof, and doors.
 Set the fan speed to low (1 or 2).
 Adjust the air flow from the air conditioning vents so that they do not blow against the microphone on the
ceiling.
 Pause after pressing the navigation TALK button, then give a voice command clearly in a natural
speaking voice. If the system cannot recognize your
command, speak louder.
 If the microphone picks up voices other than yours, the system may not interpret your voice commands
correctly.
 If you speak a command with something in your mouth, or your voice is too husky, the system may
misunderstand your command.
 Compare the system operation with a known-good vehicle. Have more than one person test the system
operation. If the known-good vehicle performs the
same, it is a characteristic of the system. 1. Turn the ignition switch to ON (II).
2. Go into the Diagnostic Menu and use the Mic Level
test under Functional Setup (see page 23-147) to
check the operation of the navigation TALK and
navigation BACK buttons.
Go to step 10.
Go to step 3.
3. Turn the ignition switch to LOCK (0).
4. Do the voice control switch test (see page 23-156).
Go to step 5.
Replace the voice control switch.
5. Disconnect the cable reel 20P connector and navigation unit connector D (5P).
6. Check for continuity between body ground and navigation unit connector D (5P) terminal No. 4.
Repair short to body ground in the wire
between the navigation unit and the voice control
switch, or replace the cable reel.
Go to step 7.

Symptom Troubleshooting (cont’d)
NOTE:
 Check the vehicle battery condition first.
 Make sure that the correct DVD color and version are installed.
 Check any official Honda service website for more service information about the navigation system.
 Check for aftermarket accessories.
1. Check the GPS icon on the navigation picture.
Do the troubleshooting for GPS icon is white
or not shown (see page 23-122).
Go to step 2.
2. Go into the Diagnostic Menu, and use the Yaw Rate test (see page 23-144) to check the yaw rate sensor.
3. Go into the Diagnostic Menu and use the Car Status test (see page 23-141) to check the vehicle speed
pulse.
The problem may be a normal characteristic.
Check to see if the problem occurs in the same
place. If it does, the problem could be in the
database. Compare to a known-good vehicle under
the same conditions. If you can duplicate the
problem, report it. Refer to the client Assistance
section of the Navigation User’s Guide, ‘‘Reporting
Errors’’.
If the problem is the yaw rate sensor, replace
the navigation unit (see page 23-155). If the
problem is the vehicle speed pulse, troubleshoot
the vehicle speed signal circuit. NOTE:
 Check the vehicle battery condition first.
 This symptom is usually caused by a defective yaw rate sensor. Perform this diagnostic when the vehicle
is cold and warm.
 Also refer to symptom troubleshooting for GPS icon is white or not shown (see page 23-122).
1. Go into the Diagnostic Menu, and use the Yaw Rate test (see page 23-144).
The system is OK.
Replace the navigation unit (see page 23-155).

probable cause.
 Go into the Diagnostic Menu, and use the Car Status test (see page 23-141) to check the status of the
display.
1. Check the DVD-ROM reading surface for scratches.
Replace the DVD-ROM.
If the problem occurs occasionally when the
system is cold, this is normal. If the problem occurs
frequently when driving, replace the navigation
unit (see page 23-155). 1. When a navigation unit is powered up for the first
time at the factory, the factory diagnosis screen (In
Line Diag) appears. Normally the factory performs
the steps necessary to verify proper operation and
terminate the factory diagnostic. Until the proper
confirmation sequence is performed, the screen
will appear every time the vehicle is started.
2. Follow the steps to prevent the screen from showingupinthefuture:
 Hold down the buttons (Menu, Map/Guide, and Cancel) for about 5 seconds (the Select Diagnosis
Items screen appears).
 Hold down the Map/Guide button for 5 10 seconds (A screen with a Complete button
appears).
 Touch Complete, and then the Return button (the system may re-boot).
 Restart the vehicle, and confirm normal operation by completing the PDI of the
navigation system Service Bulletin.
