NOTE:
 Check the vehicle battery condition first.
 Check for aftermarket accessories plugged into the vehicle accessory power sockets (including cell
phone).
 Check the connectors for poor connections or loose terminals.
 Check the radio reception in an open area. Compare it to a known-good vehicle when ever possible.Poor
reception/interference can be caused by the
following:
– The radio station is far away.
– Atmospheric conditions are unfavorable.
– Tall buildings, mountains, or high-voltage power lines are nearby.
– Aftermarket metallic wi ndow tint.
1. Turn the ignition switch to ON (II).
2. Do the seek stop test (see page 23-78).
Multipath interference or weak station.
Operation is normal. Go to step 3.
3. Check if the radio reception/interference is the same in several locations.
Go to step 4.
Multipath interference or weak station.
Operation is normal.
4. Start the engine.
5. Check the reception/interference.
Check the antenna and radio grounds. If OK,
check the charging system and the ignition
system. Go to step 6.
6. Turn the ignition switch to LOCK (0). 7. Remove the right side C-pillar trim (see page 20-75).
8. Check the connections from the AM/FM antenna
amplifier to the window antenna.
Repair the connections, or substitute a
known-good AM/FM antenna amplifier and retest.
If the symptom/condition goes away, replace the
original AM/FM antenna amplifier (see page 23-87).
Go to step 9.
9. With the help of an assistant inside the vehicle, have the assistant shine a flashlight (A) along each
antenna wire (B). Check from the outside of the
vehicle for any breaks or openings in the antenna
wires (the light shines through).
Repair the window antenna. Go to AM/FM
antenna repair (see page 23-87), or replace the rear
window (see page 20-47).
Go to step 10.

Global Positioning System (GPS) Limitations Muting LogicLCD Unit Limitations
23-91
The GPS cannot detect the vehicle’s position during the
following conditions: Metallic window tinting above the GPS antenna.
 When only three satellite signals are received (Four satellite signals are required for accurate positioning).
 When driving near high tension power lines.
 When the satellite signals are blocked by the operation of some electronic aftermarket accessories
including, but not limited to non-OEM in-dash
entertainment units (radio, CD players/changers,
radar detectors and theft recovery systems) and cell
phones placed near the navigation system.
 When the satellite control centers are experiencing problems.
The accuracy of the GPS is reduced during these
instances:  Metallic window tinting above the GPS antenna.
 When only three satellite signals are received (Four satellite signals are required for accurate positioning).
 When driving near high tension power lines.
 When the satellite signals are blocked by the operation of some electronic aftermarket accessories
including, but not limited to non-OEM in-dash
entertainment units (radio, CD players/changers,
radar detectors and theft recovery systems) and cell
phones placed near the navigation system.
 When the satellite control centers are experiencing problems. Whenever the navigation system is giving guidance,
the front speakers are muted. When the voice control
system is being used, all of the speakers are muted.
 In cold temperatures, the display may stay dark for the first 2 or 3 minutes until it warms up.
 When the display is too hot because of direct summer sunlight, it will remain dark until the temperature
drops.
 When the humidity is high and the interior temperature is low, the display may appear cloudy.
The display will clear up after some use.
 Fingerprints on the touch panel may sometimes be noticeable because of the panel’s low-reflection
coating. Clean the screen with a soft damp cloth. You
may use a mild cleaner intended for eye glasses or
computer screens. To avoid scratching the panel, do
not rub too hard, or use abrasive cleaners, or shop
towels.
 The touch panel consists of a touch sensitive resistive membrane covering the display. Unlike previous
systems, you must actually touch the display to
activate it. Never use hard or sharp implements to
operate the screen because you risk damaging the
sensing membrane. If a touch switch does not
function immediately, shift your finger slightly, and
touch it again.

CIRCUIT
The navigation system is composed of the navigation unit, the ECM/PCM (vehicle speed signal), the GPS antenna, the
microphone, the voice control switch, the XM receiver, and the climate control unit.
These units communicate with each other on the GA-Net bus.
The vehicle speed pulse is sent by the ECM/PCM. The ECM/PCM receives a signal from the countershaft speed sensor,
then it processes the signal, and transmits it to the speedometer and other systems.

Symptom Troubleshooting (cont’d)
NOTE:
 Check the vehicle battery condition first.
 Make sure the vehicle is parked outside and away from buildings.
 Refer to GPS Information (see page 23-142) for realtime satellite reception display.
 Check for window tinting above the GPS antenna and any non-OEM accessories mounted near the
navigation unit or GPS antenna.
1. Check for metallic window tint on the windshield and electronic aftermarket accessories (possibly
hidden) mounted near the GPS antenna or the
navigation unit.
Remove tint or the accessories, and
recheck.
Go to step 2.
2. Go into the Diagnostic Menu, and use the Navi System Link test (see page 23-136) to check the
GPS antenna.
Use the Navi ECU test under Unit Check
(see page 23-139) to check for a kinked, crushed, or
disconnected GPS antenna wire. If necessary, try a
known-good GPS antenna. If icon is still red,
replace the navigation unit (see page 23-155).
Check that nothing is blocking the GPS
antenna located behind the gauge assembly, and
recheck. Substitute a known-good navigation unit,
and recheck. 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 that the volume setting and voice feedback are turned ON.
 Check the connectors for poor connection or loose terminals.
 Before troubleshooting, make sure you have the navigation system 4-digit anti-theft code.
 After troubleshooting, enter the navigation system anti-theft code.
1. Press the display unit SET-UP button.
2. Check the volume setting for the navigation system.
Set the volume to an audible level.
Go to step 3.
3. Check the radio operation.
Go to step 4.
Troubleshoot the audio system.
4. Go into the Diagnostic Menu, and use the Navi System Link test (see page 23-136) to check the
radio.
Troubleshoot the audio system.
Go to step 5.
5. Test the voice control switch (see page 23-156).
Replace the navigation unit (see page 23-155).
Replace the voice control switch (see page
23-157).
Is there metallic window tint or electronic accessor ies?
Is the GPS Ant icon red? Is it set to OFF?
Can y ou hear t he r ad i o?
Is the Radio icon red?I s v oi ce cont r ol sw i t ch OK ?

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 showingupinthefuture:
 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.
Are there scratches?
