navigation components in a vehicle. If there is an open in the GA-Net or
components, components or the entire audio and navigation system may
appear inoperative.
GB (Gigabyte) A unit of memory or disk storage equal to billion bytes (1000 million bytes).
HDD Abbreviation for hard disc drive. They are sensitive to heat and it is not
recommended that they be used in the PC card slot for playing audio files.
Hertz (Hz) The unit of frequency equal to one cycle per second (cps). One kilohertz (kHz)
equals 1,000 cps; one megahertz (MHz) equals 1 million cps.
Integrated amplifier A component that combines a pre amp and a power amp into a single unit. A
receiver combines an integrated amp and a tuner into a single unit.
Jewel case The hard plastic case that contains a compact disc or DVD. Always use a jewel
case to prevent scratches on the underside of a CD or DVD.
LCD (Liquid Crystal Display) A type of digital display that changes reflectance or transmittance when an electrical field is applied to it.
Memory Circuitry or devices that hold information in electrical or magnetic form, such
as the AM/FM radio presets.
MB (Megabyte) One million bytes. Written as 1 MB. Megabytes are used as a measure of digital
storage space. For example, a CD can hold 650 MB.
Mic An abbreviation for microphone. For vehicles with navigation, the microphone
accepts navigation voice commands to control audio and navigation functions.
MP3 music files MP3 is an audio coding format. MP3 is a popular audio compression format on
the Internet and computers. CDs and PC Cards with these files can be played on
some vehicle’s audio system.
Mute When the navigation gives guidance, the front speakers are muted (no music).
When you use the voice control system, all of the speakers are muted.
Noise Unwanted random sounds like buzzing, hiss, pops, static, whine, etc.

Symptom DuplicationService Precautions
System Initialization
23-92 Navigation System
General Troubleshooting Information (cont’d)
 If you can duplicate the symptom, compare it to a
known-good vehicle. Only use a vehicle of the same
model, same year, same trim, and same software
version. If you can duplicate the symptom in the
known-good vehicle, then it is a characteristic of the
system.
 When the symptom can be duplicated, follow the self- diagnostic procedures and the appropriate
troubleshooting procedures.
 When the symptom does not reappear or only reappears intermittently, ask the client about the
conditions when the symptom occurred.
– Try to establish if outside interference may be the cause.
– Try to duplicate the symptom under the same conditions the client experienced.
– Vibration, temperature extremes, and moisture (dew, humidity) are factors that are difficult to
duplicate.
– Inspect the vehicle for aftermarket electronic devices (vehicle locators, radar detector amps, etc.)
that may be hidden.
When troubleshooting navigation system problems,
ensure that the known-good vehicle is the same
software version year and model as the vehicle being
serviced. Mixing incompatible navigation DVDs or
other system components can delay the
troubleshooting process by creating effects unrelated to
the original problem.  If you need to replace the navigation unit, inform the
customer that personal information in the navigation
system may be lost. If possible, have the client record
their personal information before the unit is replaced
On ’07-08 models you can back-up the navigation
data and transfer it to a new navigation unit. See save
users memory (see page 23-150).
 Before disconnecting the battery, make sure you have the anti-theft codes for the audio and the
navigation system, and write down the audio presets.
Also obtain any PGM-FI or transmission DTCs and
freeze frame date (which are lost when the ECM/PCM
loses power).
 When the battery is disconnected, the internal GPS clock is reset to 0:00. The clock will reset to the
correct time after the system finishes GPS
initialization.
 After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take from 10
to 45 minutes.
 Before returning the vehicle to the client, enter the audio and navigation anti-theft security code, then
enter the audio presets.
 Adjust the setup clock settings (time zone and daylight savings) in the navigation system.
If the navigation system loses power (like the battery
was disconnected), the navigation system requires
initialization. Once completed, your system is ready to
use.
This initialization requires the following:  Entering the 4-digit anti-theft security code to unlock the system
 GPS initialization (may not be needed depending of the length of time the system was without power)
 Map matching to align the GPS to a location on the map

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). NOTE:
 Check the vehicle battery condition first.
 Verify that the correct navigation unit is installed for this model. Go into the Diagnostic mode and use
Version (see page 23-149).
 Check for connectors for poor connections or loose 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.
 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.
1. Make sure the anti-theft code for the navigation system is entered.
2. Go into the Diagnostic Menu and use the Navi System Link test (see page 23-136).
Do the troubleshooting for the voice

Go to step 3.
3. Substitute a known-good navigation unit (see page 23-155), and recheck.
Replace the navigation unit (see page 23-155).
