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.

Navigation System

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).

Is the GPS icon on the map scr een?

Ar e the yaw r ate sensor and vehicle speed pulse
OK ?
