If the navigation system finds the satellites properly,
this box clears, and changes to the Disclaimer screen. If
within 10 minutes the system fails to locate a sufficient
number of satellites to locate your position, the
following screen appears.
After 30 minutes with this screen displayed, turn off the
engine, then restart the vehicle. If the Disclaimer screen
appears, the GPS initialization is complete.
NOTE:
 The average acquiring time is less than 10 minutes, but it can take as long as 45 minutes.
 If the system is still unable to acquire a signal, follow the instructions on the screen. If this screen appears
again, go to troubleshooting for the GPS icon is white
or not shown (see page 23-122).
 To bypass the GPS acquire screens, press and hold the Menu, and Zoom out keys at the same time.
Touch the Return button on the screen to exit the
diagnostic mode. This allows you to continue
troubleshooting while in the shop.
This part of the initialization matches the GPS
coordinates with a road on the map screen. To do this
part of the procedure, make sure that the navigation
system displays a map, and drive the vehicle on a
mapped road shown on the map screen. Do not enter a
destination at this time. When the name of the current
road you are driving on, appears at the bottom of the
screen, the entire procedure is complete. Your system
is now ready to use. If the navigation DVD is lost or damaged, or you need a
yearly
updated DVD, you have 2 ways to purchase one.
You can either call 888-291-4675, or order on-line at
www.hondanavi.com.
Both methods require a credit card. The DVD cannot be
ordered through the parts system. The following DVDs
will not work in this navigation system:
 Earlier model navigation DVDs (black, orange, or older vesions with a white label)
 Map software programs manufactured by other companies
 DVD movies, or DVDs containing audio recordings
 Copies of an original Navigation DVD
Update DVDs are available for purchase usually in the
fall of each year. They may contain the following:  Enhanced maps and points of interest (POI) coverage
 Fixes for minor software bugs
 Additional features
NOTE:  Map matching must be done any time the DVD is removed or replaced.
 Always order navigation DVDs on an as-needed basis. During a typical model year, each color DVD may
undergo a half a dozen software only version
upgrades to fix minor issues on some or all models
the DVD supports. This is normal. Usually only the
letter at the end of the version number changes,
while the database (maps and POIs) remain
unchanged.
 Never promise your customers future free updates.
There are no free programs for updating the
navigation DVD. Update DVDs are generally available
for purchase each fall. The on-time DVD order site
provides information when an update for a particular
color DVD is available, damaged discs are not
warrantable.

Overview
23-101
System Description
The navigation system is a highly sophisticated, hybrid locating system.
The navigation unit uses global positioning system (GPS) satellite signals, internal yaw and vehicle speed inputs, and
a map database to show where the vehicle is and to help guide you to a desired destination.
The navigation unit’s GPS receiver receives signals from the GPS, a network of 24 satellites in orbit ar ound the earth.
By receiving signals from several of these satellites, the navigation system can determine the latitude, l ongitude, and
elevation of the vehicle.
Signals from the system’s yaw rate sensor (inside the navigation unit) detects turns, and the ECM/PCM vehicle speed
pulse (VSP) and reverse signal enable the system to keep track of the vehicle’s speed and direction of travel. The
advantage of this hybrid system is that the system can track your position if either the GPS signal or the vehicle speed
signal is missing. For instance, when in a tunnel (no GPS), the speed signal is used to update your position on the map.
Alternately, while the vehicle is being transported on a ferry, GPS signals can show the vehicle position on the map as
it crosses the water.
The navigation system uses the location, direction, and speed information to display the appropriate map and
calculate a route to the destination entered. As you drive to a destination, the system provides both visual and audio
guidance. Audio guidance is sent to the audio unit, and an RGB graphics color signal is sent to the navigation display.
This navigation system also has voice recognition that allows voice control of most of the navigation, and audio
functions. The voice control switches (navigation TALK and navigation BACK buttons on the steering wheel) activate
the voice control system. The microphone on the ce iling receives your voice commands. For more information on this
feature, consult the navigation owner’s guide.
The illumination signal is used by the navigation unit to automatically switch the display mode between the Night and
Day display modes. When the headlights are on, the dash brightness control setting full brightness overrides the Night
display mode, and allows a daytime navigation display with the lights on.
When the navigation system is giving voice guidance commands, the front speakers are muted. When the voice
control system is being used (navigation TALK button pressed), all of the speakers are muted.
The internal GA-Net II bus passes information back and forth between the navigation display, the navigation unit, and
the audio system components. The information passed on this bus are touch button commands, audio muting signal,
audio (radio and XM), and any open in these bus lines can affect the navigation system or other audio accessory
operation.
The clock on the navigation display is set and maintained by the navigation unit. The time is automatically adjusted for
daylight savings, and time zone changes while driving. The time can be adjusted in setup.
Additional information is available about the navigation components following the System Diagram. A glossary of
terms that are used throughout this section follows the detailed information.
The Navigation System Manual in the glove box covers all of the system functions and settings. Use this as a resource
when evaluating a client concern.

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.

XM Receiver Accessory
(Music Link, CD changer etc.)
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 navigation unit calculates the vehicle position and guides you to the destination. The unit performs map matching
correction, GPS correction, and distance tuning. It also controls the menu functions and the DVD-ROM drive, and
interprets voice commands. With control of all these items, the navigation unit makes the navigation picture signal,
then it transmits the signal to the navigation display and audio driving instructions to the audio unit.
The navigation unit calculates the vehicle position (the driving direction and the current position) by receiving the
directional change signals from the yaw rate sensor and the travel distance signals from the PCMs vehicle speed pulse
(VSP) signal.
The map matching tuning is accomplished by indicating the vehicle position on the roads on the map. The map data
transmitted from the DVD-ROM is checked against the vehicle position data, and the vehicle position is indicated on
the nearest road. Map matching tuning does not occur when the vehicle travels on a road not shown on the map, or
when the vehicle position is far away from a road on the map.
The GPS tuning is accomplished by indicating the vehicle position as the GPS’s vehicle position. The navigation unit
compares its calculated vehicle position data with the GPS vehicle position data. If there is large difference between
the two, the indicated vehicle position is adjusted to the GPS vehicle position.
The distance tuning reduces the difference between the travel distance signal from the VSP and the distance data on
the map. The navigation unit compares its calculated vehicle position data with the GPS vehicle position data. The
navigation unit then decreases the tuning value when the vehicle position is always ahead of the GPS vehicle position,
and it increases the tuning value when the vehicle position is always behind the GPS vehicle position.
The navigation unit can calculate different routes to a selected destination. You have five options:
 Direct Route Calculate a route that is the most direct.
 Easy Route Calculate a route that minimizes the number of turns needed.
 Minimize Freeways Calculate a route that avoids freeway travel. If that is not possible, keep the am ount of
freeway travel to a minimum.
 Minimize Toll Roads Calculate a route that avoids, or minimizes travel on toll roads.
 Maximize Freeways Calculate a route that uses freeways as much as possible.
The navigation unit transmits audio driving instructions before entering an intersection or passing a junction.
The audio instructions come through the audio unit to the front speakers.
NOTE: The front speakers are muted whenever the navigation system is giving guidance commands, and all of the
speakers are muted when the voice control system is being used.
The map data (including all scale rates) is stored in the DVD-ROM. The map data includes:  Road distances, road widths, speed limits, traffic regulations, passing time at junction, distances to junctions, and the driving instructions for audio guidance.
 Latitude and longitude GPS.
