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.

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.

1. Remove the key from the ignition.
Go to step 2.

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.

Make sure that the correct navigation DVD color and 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.
