and recheck. If the symptom is gone, replace the
original navigation unit. NOTE:
 Check the vehicle battery condition first.
 Check the navigation volume level (see Owner’s Manual).
 Check the connectors for poor connections or loose terminals.
 If the Hard Error Code is stored, check the Hard Error Code troubleshooting first.

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.

Repair short to body ground in the wire
between the navigation unit and the voice control
switch, or replace the cable reel.
