Glossary

The following is a glossary of terms pertaining to the Voice Recognition Navigation System.

ITEM DEFINITION CHART

Item

Definition

AcuraLink

This device receives information from the XM satellites and passes XM audio
information to the audio unit. In addition, traffic information is sent to the navigation
unit.

Address Book

The HFL system can import a copy of the phone book from and approved HFL
compatible phone and can display the imported phone book on the navigation screen
as the address book. See the Owner's Manual for more information.

B-CAN

Body CAN Bus (see CAN below)

Breadcrumbs
(white dots)

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.

CAN

Controller Area Network. This communication network allows processors in the
vehicle to send/receive information. The fuel pulses used by the MID trip computer
are received from the PCM using the F-CAN (Fast Controller Area Network) bus.

CPU

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

CSS

Countershaft (Output) Speed Sensor. This sensor reads the output shaft speed at the
transmission and provides a speed pulse to the PCM.

Database

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

DBW

Drive By Wire. Allows electrical control of the throttle without the need of a

mechanical linkage.

DCA

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.

DTC

Diagnostic Trouble Codes. Use the PGM Tester, or HDS tablet to obtain, and
troubleshoot the cause of these codes.

Dead
Reckoning

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

Digitized Road

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 after 1/2 mile, the "breadcrumbs" will
appear.

Disclaimer
Screen

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

DVD or DVD-
ROM

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 an
update DVD.

ECM

Engine Control Module. Typically referred to as the ECM.

FAQ

Frequency Asked Questions. Seethe Navigation Owner's Manual for a list of the
client FAQs, and troubleshooting information.

F-CAN

Fast CAN Bus (see CAN above)

GA-NET

The GA-Net allows the audio unit to communicate with all the audio and navigation
components in a vehicle. If there is an open in the GA-Net, components or the entire
audio and navigation system may appear inoperative.

GPS

Global Positioning System. A network of 24 satellites in orbit around the earth. The
navigation system can simultaneously receive signals from up to 12 satellites to
accurately position the vehicle on the map.

GPS

HDS

Honda Diagnostic System. A hand held tablet PC used for diagnosing vehicle
problems. This device can be used to obtain DTC codes for diagnosis of the
navigation system and CAN related problems.

HIP
(AcuraLink)

This device receives information from the XM satellites and passes XM audio
information to the audio unit. In addition, traffic information is sent to the navigation
unit.

HFL

HandsFreeLink uses Bluetooth technology as a wireless link between it and a
Bluetooth compatible cell phone. See the vehicle Owner's manual or Quick Start
Guide for more information.

H/U

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

Initialization

This refers to the period needed to re-acquire the GPS satellite orbital information
whenever the navigation system power has been disconnected. This can take from 10
to 45 minutes.

Interface Dial

This control device consists of a rotating knob and the buttons surrounding it. This
device allows control of the navigation, audio, and climate functions displayed on the
screen.

LCD

Liquid Crystal Display (the navigation screen)

Map Matching 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

Navi

Abbreviation for the Navigation System.

Off Road
Tracking

See Off Road Tracking (Breadcrumbs) .

Off Route

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"

Outlying Areas

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.

Paired

Linking your cell phone to the HFL

PC Card Slot

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
