System Description (cont’d)
The global positioning system (GPS) enables the navigation system to determine the current position of the vehicle by
using the signals transmitted from the satellites in orbit around the earth. The sate
llites transmit the satellite
identification signal, orbit information, transmission time signal, and other information. When the GPS receiver
receives a signal from four or more satellites simultaneously, it calculates the current position of the vehicle based on
the distance to each satellite and the satellite’s positions in its respective orbit.
The precision of the GPS varies according to the number of satellites from which signals are received and the view of
the sky. The accuracy is indicated by the color and shape of the GPS icon shown on the display.
No GPS icon None Faulty reception The GPS can’t be utilized due to a faulty GPS receiver, open in the wire, or other
fault or interference.
White GPS icon 2 or less Impossible to detect vehicle positionGPS function is normal. The satellite
signals received by the GPS are too few to
detect the vehicle position.
Green GPS icon 3 Vehicle position detectable in 2 dimensionsThe longitude and latitude of the vehicle
position can be detected. (Less precise
than detection in three dimensions)
4 or more Vehicle position detectable in 3 dimensions (elevation
displayed) The longitude, latitude and the altitude of
the vehicle position can be detected. (More
precise than detection in two dimensions)
The GPS antenna amplifies and transmits the signals received from the satellites to the GPS receiver.
The GPS receiver is built into the navigation unit. It calculates the vehicle position by receiving the signal from the GPS
antenna. The current time vehicle position and signal reception condition is transmitted from the GPS receiver to the
navigation unit to adjust vehicle position.

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.

23-108Navigation System
System Description (cont’d)
The audio unit receives the audio driving instructions from the navigation unit, and transmits the instructions through
the front speakers even when the audio system is in use.
The navigation display uses liquid crystal display (LCD). The LCD is a 6.5-inch-diagonal, thin film transistor (TFT),
stripe type with 65,536 color, The color film and fluorescent light are laid out on the back of the liquid crystal film. The
touch sensor on the front of the LCD consists of a touch sensitive resistive membrane with an infinite number of
possible touch locations.
The microphone (on the ceiling, near the front map light) receives voice commands and transmits them to the
navigation unit for interpretation.
Activates the voice control system in the navigation unit to accept voice commands.
Returns the display to the previous screen (similar function as the CANCEL button).

The following is a glossary of terms pertaining to the Voice Recognition Navigation System.Active noise cancellation
(ANC) 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.
Address Book The HFL system can import a copy of the phone book from and approved HFL compatible phone and display the imported phone book on the navigation screen as the address book. See the Owner’s Manual for more

This diagram below shows and over view of the navigation diagnostic features starting at the center and working
outward in layers. The diagram starts with Key on. From any of the navigation Map or Menu screens, press and
simultaneously hold the keys Menu, MAP/GUIDE, and Cancel.
Finally, the diagram shows the available diagnostic menu choices, starting at the bottom left, and moving clockwise.
In most cases, do not clear or change settings in any diagnostic screen unless instructed to do so in the explanation, or
by the factory. If the factory asks you to insert a PCMCIA memory card into the PC card Slot, then the features specified
on the diagram with PC card are available.(cont’d)
