Navigation System

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 displays the current street name in the bottom-shaded area.

Mic

Abbreviation for the microphone used for receiving voice commands. It is located near the map light in the
ceiling. The ANC circuit may also use it to check its tuning.

MID

Multi-Information Display

Maneuver Window. While on

route to a destination, this window displays information about the next

maneuver.

Navi

Abbreviation for the Navigation System.

Off-road tracking

See bread-crumbs.

Off route

This occurs when the user leaves mapped roads. Off road tracking dots (bread-crumbs) are displayed If the
option is enables in the setup menu. The user can use them to return to a mapped road. The bottom of the
navigation screen displays 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 the have not been verified.

Paired

Linking your call 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
times, if opened, an error message is displayed on the screen.

PCM

Powertrain Control Module. This unit supplies the navigation system speed signal, also refered to as PCM.

PCMCIA

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

Personal Identification Number, a random 4 digit number created by the customer to protect personal
information.

POI

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

Polygon

Colored areas on the map screen denoting parks, schools, etc. See the Navigation System Manual Driving to
Your Destination for a list of the assigned colors.

QWERTY

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

SCS connector

The service check signal 2-pin connector used to put the navigation system into the diagnostic mode.

navigation unit serial number. You can find the serial number on the diagnostic screens (unit check, Navi
ECU), or on the underside of the navigation unit.

Tuning

A continual update of internal navigation system scaling factors. See the individual sensor tuning
discussions under either System Description, or System Diagnosis Mode (see page 23-297).

Unverified streets

These streets have not been verified for turn restrictions, one-way, etc. They appear light brown on the map.
You can enter address destinations in these areas, but depending on your Unverified. Routing choice in
setup, voice guidance may end at the last verified street closest to your destination.

USB

Universal Serial Bus. The USB is used for playing the compressed audio files (MP3, WMA, and AAC) on the
external device through the audio unit.

Verified streets

These streets consist of the detailed metropolitan coverage areas, and other inter-town connection roads.
These roads are shown in black or red on the map. (interstates are red)

Voice Recognition. This allows voice control of many of the navigation functions. The hardware consists of
the microphone, voice control switch (navigation TALK/BACK buttons), and the center speaker. See the
overview for more information.

VSP

Vehicle Speed Pulse. This pulse signal coming from the PCM (VIA the CSS) is used to update the Vehicle
position on the map. These pulses do not indicate direction (forward or backward). When in reverse, the
navigation receives a signal and directs the VP to move backwards on the map.

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.

This diagram below shows all of the navigation diagnostic features available for system troubleshooting. The diagram
starts at the center, and works outward in layers.

Access to the diagnostic features begins by starting the vehicle. This is necessary so the system can check the other
systems connected by various busses. After starting the vehicle you can enter the diagnostic mode either by pressing
and holding MENU, MAP/GUIDE, and CANCEL.

The main menu screen allows 2 checking modes - one automatic, and one manual:

• The automatic diagnostic check starts when you select SELF DIAGNOSTIC MODE. The system runs for several

seconds, and reports any issues with Red icons. Rotate the interface dial and select the icon you wish obtain the
problem details.

• The manual diagnostic check is selected from the main menu by selecting DETAIL INFORMATION AND SETTING.

The traditional diagnostic menu is displayed. This allows you to obtain additional details as instructed in the
troubleshooting procedures.

NOTE: Do not clear or change settings unless specified by either the Service Manual troubleshooting procedures or by
the factory. Otherwise, you may accidentally delete customer information, or remove the latest flash software version
installed by the factory.
