SYSTEM DESCRIPTION
Revision: 2007 April2007 M35/M45

Map-matching does not function correctly when a road on which
the vehicle is driving is new and not recorded in the map DVD-
ROM, or when road pattern stored in the map data and the
actual road pattern are different due to repair.
When driving on a road not present in the map, the map-match-
ing function may find another road and position the vehicle mark
on it. Then, when the correct road is detected, the vehicle mark
may change to it.

Effective range for comparing the vehicle position and travel
direction calculated by the distance and direction with the road
data read from the map DVD-ROM is limited. Therefore, when
there is an excessive gap between current vehicle position and
the position on the map, correction by map-matching is not possible.
GPS (Global Positioning System)
GPS (Global Positioning System) was developed for and is con-
trolled by the US Department of Defense. The system utilizes GPS
satellites (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at an altitude of approximately 21,000 km
(13,100miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver calculates the vehicle's position in
two dimensions (latitude/longitude), utilizing the altitude data calcu-
lated previously with radio waves from four or more GPS satellites
(two-dimensional positioning).
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:

In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position
changes.

The accuracy can be even lower depending on the arrangement of the GPS satellites utilized for the posi-
tioning.

Position detection is not possible when vehicle is in an area where radio waves from the GPS satellite do
not reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves from
the GPS satellites may not be received when some object is located over the GPS antenna.
NOTE:

Even a high-precision three dimensional positioning, the detection result has an error about 10 m (30 ft).

Because the signals of GPS satellite is controlled by the Tracking and Control Center in the United States,
the accuracy may be degraded lower intentionally or the radio waves may stop.
HANDS-FREE PHONE

AV (NAVI) control unit has Bluetooth module. It can perform wireless hands-free telephone calls using a
cellular phone in vehicle compartment.

5 or more portable phones can be registered into the AV (NAVI) control unit.
REAR VIEW MONITOR

The small CCD camera is equipped into the rear end of the vehicle. The rear view monitor that displays
the area behind the vehicle while backing up is equipped.

Guiding lines indicating side and rear clearances are provided in the rear view monitor image, which
allows the driver to more easily judge distances between the vehicle and objects in the display. The possi-
ble route lines that indicate the possible route according to the steering angle are provided to help backing
up when parking.

Image quality of the rear view image and of the navigation screen can be adjusted separately.

AUDIO UNIT
Base System

It receives the TEL voice signal and voice guidance signal from
AV (NAVI) control unit and output them to the front speaker.

When the TEL voice and voice guidance is output, it controls the
volume of each speaker.
BOSE 2ch System
It receives the TEL voice signal from AV (NAVI) control unit and out-
put it to the BOSE amp.
BOSE Surround 5.1ch System

It receives the TEL voice signal from AV (NAVI) control unit and
output it to the BOSE amp.

DVD player receives the received AUX sound and the downmix
sound of DVD player, and then sends them to the BOSE amp.
BOSE AMP
BOSE 2ch System

It amplifies the sound signal from the audio unit and output it to
each speaker.

It receives the voice guidance signal from AV (NAVI) control unit
and output it to the front speaker.

It controls sound volume of each speaker when outputting TEL
voice and voice guidance.

It subjects to AudioPilot® processing when receiving sound sig-
nal from microphone for AudioPilot
® .

BOSE Surround 5.1ch System

It amplifies the sound signal from the audio unit and the DVD
sound signal from DVD player, and then output them to each
speaker.

It receives the voice guidance signal from AV (NAVI) control unit
and output it to the front speaker.

It controls sound volume of each speaker when outputting TEL
voice and voice guidance.

It subjects to AudioPilot® processing when receiving sound sig-
nal from microphone for AudioPilot
® .

It subjects to Centerpoint® processing.
SATELLITE TUNER

The satellite tuner is connected with the audio unit via communi-
cation line.

It sends the received sound signal from the satellite radio
antenna to the audio unit.
AV CONTROL UNIT (WITHOUT NAVI)

It controls each unit of the system by the operation signal from
the multifunction switch and sends the image signal of operating
condition or vehicle information, etc. to the front display unit.

It receives the TEL input voice or the input voice at voice control
from the microphone. It receives the received TEL voice, and
then sends it to the audio unit.

It sends the voice guidance signal to BOSE amp (BOSE system)
and audio unit (BASE system).
NAVI CONTROL UNIT (WITH NAVI)

It controls each unit of the system by the operation signal from
the multifunction switch and sends the image signal of operating
condition or vehicle information, etc. to the front display unit.

It receives the TEL input voice or the input voice at voice control
from the microphone. It receives the received TEL voice, and
then sends it to the audio unit.

It sends the voice guidance signal to BOSE amp (BOSE system)
and audio unit (BASE system).

Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining this data with the data contained in the DVD-ROM map.
Location information is shown on liquid crystal display panel.

CAN Communication System DescriptionNKS0048B
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS0048C
