Definition

Off road tracking dots that can be followed on the map to retrace your route back to a

mapped (digitized) road. This function can be turned on/off in Setup screen 1 .

Central Processing Unit. The main device within the navigation unit that coordinates the
rest of the electronic functions.

This consists of the Map data, and the POI (Points Of Interest) data stored on the DVD.

Detailed Coverage Area. Main metropolitan areas in the Lower 48 states, and Canada are
mapped to this level. See the Navigation Owner's manual for a list of these areas.

Diagnostic Trouble Codes. Use the HDS tablet to obtain, and troubleshoot the cause of

these codes.

The use of the speed signal, and yaw rate sensor to position the vehicle on the map even
when the GPS signal is obscured by tall buildings, or while driving in a tunnel.

A road that appears on the navigation screen. The road name will appear at the bottom of
the navigation screen. If the user drives "off road" the navigation system will display

"Not on a digitized road", and if 1/2 mile, then "breadcrumbs" will appear.

Screen containing cautionary information. It is meant to read carefully and acknowledged
by the customer when using the navigation system.

Digital Versatile Disk. The navigation program and database resides on this disk. See the
Navigation Owner's Manual for information on how to order a replacement or update
DVD.

Engine Control Module. Typically referred to as the PCM

Frequency Asked Question. See the Navigation Owner's Manual for a list of the customer
FAQs, and troubleshooting information

Proprietary communication bus. This serial bus connects the audio unit, navigation unit,
display unit, and XM receiver. Signals passed on this bus include audio muting requests,
navigation and display unit buttons, control commands, and XM control sequences.

Global Positioning System. A network of 24 satellites in orbit around the earth. The navi-
gation system can simultaneously receive signals from up to 1 2 satellites to accurately
positioning the vehicle on the map.

Honda Diagnostic System. A hand held tablet PC for use in diagnosing vehicle problems.

This device can be used to obtain DTC codes for diagnosis of navigation system CAN

related problems.

Head Unit. The navigation system display unit assembly in the dash.

This refers to the period needed to re-acquire the GPS satellite orbital information when-
ever the navigation system power has been disconnected. This can take from 1 0 to 45

minutes.

Liquid Crystal Display (the navigation screen)

The received GPS information allows the navigation system to position the vehicle on the

map. Map matching has occurred if the map screen is displaying the current street name
in the bottom-shaded area.

Abbreviation for the microphone used for receiving voice commands. It is located near
the map light in the ceiling

Abbreviation for the Navigation System

This occurs when the user leaves mapped roads. Off road tracking dots ("breadcrumbs")
are displayed if the option is enabled in Setup. The user can use them to return to a

mapped road. The bottom of the navigation screen will say "Not on a digitized road"

These are rural areas that typically have only their main roads mapped. All other roads
are shown in light brown for reference only, since they have not been verified.

The PC Card (PCMCIA, type II) slot is for factory use only. Make sure that the sliding door

is closed at all items, if opened, an error message is displayed on the screen.

Powertrain Control Module. This unit supplies the navigation system speed signal.

An computer industry defined term referring to the PC Card slot standard.

Personal Identification Number, a random 4 digit number created by the customer to pro-

tect personal information

Point Of Interest. These are the businesses, schools etc. found under the "places" option
on the main menu

Colored areas on the map screen denoting parks, schools etc. See the Navigation
Owner's Manual "Traveling to Your Destination" for a list of the assigned colors.

Keyboard layout resembling the typewriter keys. The keyboard layout can be changed to
an alphabetical layout in the Setup mode.

The 2-pin connector used to put the navigation system into the diagnostic mode

Code needed to activate the navigation system. The security code can be obtained from

the "IN" by entering the navigation system control serial number. The serial number can

be found from the diagnostic screens (Unit Check, Navi ECU), or from the under side of

the control unit.

The sides of the navigation screen have 9 vertical and 20 horizontal infrared beams that
are interrupted by the user's finger to select the desired function.

A continual update of internal navigation system scaling factors. See the individual sen-
sor tuning discussions under either "System Description", or "System Diagnosis Mode"

(see page

23-40

) in this manual.

These streets have not been verified for turn restrictions, one-way, etc. They are shown in

light brown on the map. You can enter address destinations in these areas, but voice
guidance ends at the last verified street closest to your destination.

This unit provides emergency, and other specialty services over a cellular link. There is a

monthly charge associated with this feature. The unit has it's own GPS antenna, and cel-
lular phone antenna. When in use, the navigation guidance is muted, and voice control
system is disabled.

XM Radio for this model. This provides additional channels of audio entertainment for a
fee. The XM radio receiver is located in the trunk, and has its own independent satellite,
and terrestrial antennas (for receiving the broadcasts when satellite signals are temporari-

ly blocked).

Definition

These streets consist of the detailed metropolitan coverage areas, and all other intertown
connection roads. These roads are shown in black on the map.

Vehicle Position. When in map mode, this circular icon shows the vehicle position on the

map. Touch this icon to show the latitude, longitude, and elevation of your current posi-

tion.

Voice Recognition. This allows voice control of many of the navigation functions. The

hardware consists of the microphone, steering wheel (Talk/Back) buttons, and the front
speakers. See the overview for more information.

Vehicle Speed Pulse. This pulse signal coming from the PCM is used to update the
Vehicle position on the map. These pulses do not indicate direction (forward or back-

ward). When in reverse, the navigation receives a signal from the reverse relay and
directs the VP to move backwards on the map.

Vehicle Speed Sensor. This sensor reads the output shaft speed at the transmission and,

provides a speed pulse to the PCM. The PCM sends this pulse to the navigation system

and speedometer.

This device is located in the navigation system control unit and senses the side-to-side
twisting force generated when the vehicle turns. See a detailed description of how this

sensor works in this manual (see page

Diagnostic Test: Navigation System Link

1. Check the No. 56 (7.5A) fuse in the under-hood fuse/

relay box and No. 4 (10A) fuse in the under-dash fuse/
relay box, and reinstall the fuses if they are-OK.

Are the fuses OK?

YES—Go to step 2.

NO—Replace the fuse and recheck.

2. Turn the ignition switch to ACC (I).

3. Operate the radio and listen to the audio.

Can audio be heard?

YES—Go to step 4.

NO—Check the ACC circuit.

4. Turn the ignition switch ON (II).

5. Measure the voltage between body ground and navi-

gation unit connector C (8P) terminals No. 1 and No.
2 individually.

Wire side of female terminals

Is there battery voltage?

YES—Go to step 6.

NO—If the + B wire does not have voltage, repair
open in the wire between the under-hood fuse relay
box and the navigation unit.
If the ACC wire does not have voltage, repair open in
the wire between the under-dash fuse relay box and

the navigation unit.

6. Check for continuity between navigation unit connec-

tor C (8P) terminal No. 4 and body ground.

NAVIGATION UNIT CONNECTOR C (8P)

Wire side of female terminals

Is there continuity?

YES—Go to step 7.

NO—Repair open in the wire between the navigation
unit and body ground (G603).

7. Turn the ignition switch OFF.

8. Perform the forced starting of the display (see page
