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.

Replace the HFL-voice control switch.
5. Disconnect the HFL-voice control switch 5P connector and navigation unit connector D (12P).
6. Check for continuity between body ground and navigation unit connector D (12P) terminal No. 1.
Repair short to body ground in the wire
between the navigation unit and the voice control
switch, or replace the cable reel.

Symptom Troubleshooting (cont’d)
NOTE:
 Check the vehicle battery condition first.
 Check that the GPS antenna is plugged in.
 This is not the same condition as when driving off- road (or on a fire or logging road). This condition is
caused by a loss of map matching from a bad sensor
input. Check for after market window tinting or other
objects that can block the GPS signal. Always do the
Map matching (see page 23-269) before proceeding
with the troubleshooting.
 Make sure that the correct DVD color and version are installed.
 Inspect the DVD for dirt or damage.
 Check any official Honda service website for more service information about the navigation system.
 Check the GPS signal reception in an open area.
1. Check the GPS icon on the navigation screen.
Do the troubleshooting for GPS icon is white
or not shown (see page 23-341).
Go to step 2. 2. Go into the Self-Diagnosis Mode, and use the Yaw
Rate test (see page 23-314) to check the yaw rate
sensor.
3. Go into the Self-Diagnosis Mode, and use the Car Status test (see page 23-315) to check the vehicle
speed pulse.
The condition may be normal. Check to see if
the condition occurs in the same place in a known-
good vehicle. If it does, the problem could be in the
database.Gotostep4.
If the problem is the yaw rate sensor, replace
the navigation unit (see page 23-355). If the
problem is the vehicle speed pulse, check for an
open in the wire between the navigation unit and
the ECM/PCM (VSP signal). If the wire is OK,
substitute a known-good navigation unit, and retest.
If the problem goes away, replace the original
navigation unit. If the problem is still present,
replace the ECM/PCM.
4. Substitute a known-good navigation unit, and check to see if the problem occurs in the same
place.
The problem is in the database. Report the
problem according to the Navigation System
Manual under Reporting Errors.
Replace the original navigation unit (see page
23-355).
