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 Navigation System Manual for a list of

common DVD screen error messages and the
probable cause.

• Go into the Diagnostic Menu, and use the Car Status

test (see page 23-141) to check the status of the
display.

1. Check the DVD-ROM reading surface for scratches.

Replace the DVD-ROM.

If the problem occurs occasionally when the

system is cold, this is normal. If the problem occurs
frequently when driving, replace the navigation
unit (see page 23-155).

1. When a navigation unit is powered up for the first

time at the factory, the factory diagnosis screen (In
Line Diag) appears. Normally the factory performs
the steps necessary to verify proper operation and
terminate the factory diagnostic. Until the proper
confirmation sequence is performed, the screen
will appear every time the vehicle is started.

2. Follow the steps to prevent the screen from

showing up in the future:

• Hold down the buttons (Menu, Map/Guide, and

Cancel) for about 5 seconds (the Select Diagnosis
Items screen appears).

• Hold down the Map/Guide button for 5

10 seconds (A screen with a Complete button
appears).

• Touch Complete, and then the Return button (the

system may re-boot).

• Restart the vehicle, and confirm normal

operation by completing the PDI of the
navigation system Service Bulletin.

Navigation System

NOTE:

• Check the vehicle battery condition first.
• Check the connectors for poor connection or loose

terminals.

• Before troubleshooting, get the navigation system

anti-theft code.

• After troubleshooting, enter the navigation system

anti-theft code.

• Full brightness on the instrument panel brightness

control with the head lights turned on causes the
system to stay in the day mode, even when the lights
are on.

1. Make sure the instrument panel brightness control

is not on full brightness. Turn the headlights on and
adjust the dash brightness to the middle range.

2. Change the day/night mode under Set-up to AUTO,

and recheck.

The system is OK at this time.

Go to step 3.

3. Go into the Diagnostic Menu and use the Car Status

test to check for an ILL signal (see page 23-141).

Replace the navigation unit (see page 23-155).

Check the ILL

circuit between the

navigation unit and the No. 14 (7.5 A) fuse in the
under-dash fuse/relay box.

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.

1. Start the engine and turn the ignition switch to

LOCK (0), then turn the ignition switch to ON (II).

The system is OK at this time.

Check the DVD for scratches or damage, and

the navigation unit for water damage. If OK, go into
the Diagnostic Menu and do all of the Unit Check
tests (see page 23-139). Also check for low battery
charge or poor charging system performance.

switch in LOCK (0)

Navigation cannot control audio system

YES

23-129

NOTE:

• Check the connectors for poor connections or loose

terminals.

• Before troubleshooting, get the navigation system

anti-theft code, then write down the audio presets.

• After troubleshooting, re-enter the anti-theft code,

and re-initialize the navigation system, then enter the
audio presets.

• Check for aftermarket accessories that use the same

power circuit. A feedback can cause this problem.

1. Remove the key from the ignition.

Go to step 2.

The system is OK at this time.

2. The vehicle may have been used as a

demonstration vehicle at an event like an auto
show. In these events, power is often jumpered to
the navigation system so that the ignition key is not
needed in the vehicle. At the end of the show, the
jumper wire may not have been removed. Check
the navigation unit connector A (17P) for a non-
factory jumper wire in series with the factory cable.

Remove the jumper wire, and re-test. Return

the jumper wire to Tech Line.

Go to step 3.

3. Check if the audio unit works.

Troubleshoot the ACC circuit for a short to

power with another circuit.

Replace the navigation unit (see page 23-155).

this model. Go into the Diagnostic mode and use

terminals.

• Before troubleshooting, make sure you have anti-

theft codes for the navigation system.

• After troubleshooting, enter the anti-theft codes for

the navigation system.

version are installed.

• Inspect the navigation DVD for dirt or damage.
• Check any official Honda service website for more

service information about the navigation system.
