(With navigation)
The navigation system allows voice control of the audio, XM, PC card, and CD player. Voice control commands are
communicated on the GA-Net (audio unit). When using the navigation TALK/BACK button, the audio is muted on all
speakers and you get navigation sound on the front channels. When using the navigation or route guidance (RG), the
front speakers give the navigation sound and the rear speakers continue to play. For more information, see the
navigation section. The outline of the interruption function is shown in this table.

The audio unit can play digital music from portable audio players, USB drive, etc. When the device is plugged into the
USB adapter. The audio unit uses the GA-NET to allow you to control the device from the audio unit when searching
and playing the files. Not all players and player functions work with the USB adapter. Please see the owner’s manual
for more information.
The GA-Net bus passes audio and navigation commands throughout the navigation and audio components.
These commands include navigation touch screen and hard button signals, audio/XM selections by voice, and XM
station and music title names. Because the entire bus is daisy chained between components (see diagram), any open
or short in the GA-Net bus harness will cause any or all of these functions to become inoperative. Naturally the
addition of any audio accessory must maintain the continuity of the GA-Net bus by installing the Y cable included with
the accessory kit.

Active noise cancellation The active noise cancellation system cancels some of the vehicle noise. This occurs in the 1,500 2,400 rpm range. Microphones detect the low frequency
sound, and the system outputs a canceling sound from the audio speaker.
AM (Amplitude Modulation)
Amplifier A device that increases the level of a signal by increasing the current or voltage.
Antenna A device used to send or receive electromagnetic waves thr ough the air.
ATA (PC Card) A type of card that has been tested for use in playing WMA, and MP3 music files in the PC Card slot. Sizes of up to 1 GB have been tested.
Audio remote switch The switches on the steering wheel that control the audio system.
Auxiliary jack Allows the customer to use a portable audio device to i nput audio recordings.
Balance A control that changes the relative volume of the left and right channels.
Band A range of frequencies between two definite limits. Bands are assigned by the Federal Communications Commission for specific uses.

magazine (with CDs stacked in a container).
CD player A com ponent designed to play compact disc recordings using a laser optical
pickup. The signal from a CD player usually requires amplification.
Decibels (db)

Error Codes
The audio system displays error codes when a problem is detected with the disc changer, the disc, the tape player, the
XM radio, or the anti-theft code.
This is not a complete list of audio error codes. Refer to symptom troubleshooting, or go to any official Honda service
website for more service information.
DISC ERROR The system cannot read the disc because an audio or video DVD
is inserted into the unit. The CD
may be inserted upside down. Verify that the unit functions with a standard
mass production CD.
MECH ERROR There is a problem with the mechanism A CD label may be
jammed in the mechanism. Replace the navigation unit.

inserted.Press the EJECT button and hold it for 5
seconds. If the disc does not eject, try again. If
the disc still won’t eject, replace the unit.




HEAT ERROR CD player is too hot. This can
happen if the vehicle is parked
in the sunlight all day. The unit should function normally when it
cools off.

23-266Navigation System
General Troubleshooting Information
Refer to the navigation system manual for the
navigation system operating procedures.
The navigation system and audio unit have a coded
theft protection circuit. Make sure you have the anti-
theft security code before:
 Disconnecting the battery.
 Disconnecting the navigation unit connector A (24P) and C (8P).
 Removing the No. 23 (10 A) fuse from the under-hood fuse/relay box.
After service, reconnect power to the navigation unit,
and turn the ignition switch to ON (II). Enter the 4-digit
anti-theft security code, then select Done.
If the code cannot be found, use the interactive Network
(iN) to look it up. You can view the serial number in one
of the ECU Info diagnostic screens (see page 23-305).
Alternatively, you can find the serial number on the
underside label which is located on the navigation unit
in the trunk.
When replacing the navigation unit, be sure to give the
customer the new anti-theft security code.
Certain circumstances and system limitations will result
in occasional vehicle positioning errors. Some client’s
may think this indicates a problem with the navigation
system when, in fact, the system is normal. Keep the
following items in mind when interviewing client’s
about symptoms of the navigation system.
The limitations of the self-inertial portion of the
navigation system (the yaw rate sensor and the vehicle
speed signal) can cause discrepancies between the
vehicle’s actual position and the indicated vehicle’s
position (GPS vehicle position). The following circumstances may cause vehicle
positioning errors:
 Moving the vehicle with the engine stopped and the vehicle stopped, such as by ferry or tow truck, or if
the vehicle is spun on a turn table.
 Tire slippage, changes in tire rolling diameters, and some driving situations may cause discrepancies in
travel distances. Examples of this include:
– Continuous tire slippage on a slippery surface
– Driving with snow chains mounted
– Abnormal tire pressure
– Incorrect tire size
– Frequent lane changes across a wide highway
– Continuous driving on a straight or gently curving highway
– Very bumpy roads
 Tolerances in the system and map inaccuracies sometimes limit how precisely the vehicle’s position
is indicated. Examples of this include:
– Driving on roads not shown on the map (map matching is not possible)
– Driving on a road that winds in one direction, such as a loop bridge, an interchange, or a spiral parking
garage
– Driving on a road with a series of sharp hair-pin turns
– Driving near a gradual highway exit or transition
– Driving on one of two close parallel roads
– Making many 90 degree turns
The GPS cannot detect the vehicle’s position or
elevation during the following instances:  For the first 5 to 10 minutes after reconnecting the battery (this process can take as long as 45 minutes).
 When the satellite signals are blocked by tall buildings, mountains, tunnels, large trees, inside
parking structures or large trucks.
 When the GPS antenna is blocked by metallic window tinting or by an object placed above it in the
vehicle. The GPS antenna requires a clear
unobstructed view of the sky.
 When there is no satellite signal output (signal output is sometimes stopped for sate llite servicing).
 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.

ÎGA-Net Bus Configuration
Muting Signal Logic
23-282Navigation System
System Description (cont’d)
Navigation unit
Accessory
(CD changer etc.)
XM receiver
USB Adapter
The GA-Net bus passes audio and navigation commands throughout the navigation and audio components.
These commands include audio/XM selections by voice, and XM station and music title names. Because the entire bus
is daisy chained between components (see diagram below), any open or short in the GA-Net bus harness will cause
any or all of these functions to become inoperative. The addition of any factory audio accessory must maintain the
continuity of the GA-Net bus by installing the Y cable included with the accessory kit.
The audio muting logic is orchestrated by the navigation unit. The navigation unit determines what audio source has
priority to use the speakers.
The priority of the audio sources is as follows:
HandsFreeLink has the highest priority, followed by, navigation, and finally the radio/CD player. The priority is passed
by HandsFreeLink to the navigation unit by dedicated mute wires. The navigation mute signal is passed to the stereo
amplifier.
The navigation unit temporarily disables the voice control buttons, but allows guidance to be heard. In addition, the
navigation unit suppresses the output from the XM receiver, disc pl ayer, or other audio accessories.
When the navigation system sends out a voice route guidance command, the rear speakers are muted, and the
navigation voice is heard in the front speakers.
When the navigation voice control system and HandsFreeLink is use, the rear speakers are muted, and the navigation
voice prompts are heard from the front speakers.
