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
Setup (see page 23-309) to check the operation of
the navigation Talk and Back buttons.
