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 anti-theft codes.

• After troubleshooting, enter the anti-theft codes for

the navigation system.

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 like known-good vehicle performs
the same, if is a characteristic of the system.

1. Turn the ignition switch to ON (II).

2. Go into the Self-Diagnosis Mode select, Mic Icon

Menu, and use the Mic Level test under Functional
