The audio system consists of the following components

• AV control unit

• Display unit

• BOSE speaker amp.

• Window antenna

• Steering wheel audio control switches

• A/C and AV switch assembly

• Front door speakers

• Front tweeters

• Rear door speakers

• Rear tweeters

• Subwoofer

When the audio system is on, radio signals are received by the window antenna. The AV control unit then

sends audio signals to the BOSE speaker amp. The BOSE speaker amp. amplifies the audio signals before

sending them to the front door speakers, front tweeters, rear door speakers, rear tweeters and the subwoofer.

Refer to Owner's Manual for audio system operating instructions.

SATELLITE RADIO SYSTEM

The satellite radio system consists of the following components

• Satellite antenna

• AV control unit

When the satellite radio system is on, radio signals are supplied to the AV control unit from the satellite

antenna. The AV control unit then sends audio signals to the BOSE speaker amp.

Refer to Owner's Manual for satellite radio system operating instructions.

SPEED SENSITIVE VOLUME SYSTEM

Volume level of this system goes up and down automatically in proportion to the vehicle speed. The control

level can be selected by the customer. Refer to Owner's Manual for operating instructions.

System Description

INFOID:0000000005259501

NOTE:

Refer to NAVI System Owner's Manual for system operation.

The navigation system periodically calculates the vehicle's current position according to the following three

signals: Travel distance of the vehicle as determined by the vehicle speed sensor, turning angle of the vehicle

as determined by the gyroscope (angular velocity sensor), and the direction of vehicle travel as determined by

the GPS antenna (GPS information).

The current position of the vehicle is then identified by comparing the calculated vehicle position with map data

read from the map data, which is stored in the hard disk drive (HDD)(map-matching), and indicated on the

screen with a current-location mark.

By comparing the vehicle position detection results found by the

GPS and by map-matching, more accurate vehicle position data can

be used.

The current vehicle position will be calculated by detecting the dis-

tance the vehicle moved from the previous calculation point and its

direction.

TRAVEL DISTANCE 

Travel distance calculations are based on the vehicle speed input signal. Therefore, the calculation may

become incorrect as the tires wear down. To prevent this, an automatic distance fine adjustment function has

been adopted.

TRAVEL DIRECTION 

Change in the travel direction of the vehicle is calculated by a gyroscope (angular velocity sensor) and a GPS

antenna (GPS information). As the gyroscope and GPS antenna have both merit and demerit, input signals

from them are prioritized in each situation. However, this order of priority may change in accordance with more

detailed travel conditions so that the travel direction is detected more accurately.

MAP–MATCHING

Map–matching is a function that repositions the vehicle on the road

map when a new location is judged to be the most accurate. This is

done by comparing the current vehicle position, calculated by the

method described in the position detection principle, with the road

map data around the vehicle, read from the map data stored on the

HDD.

Therefore, the vehicle position may not be corrected after the vehicle

is driven over a certain distance or time in which GPS information is

hard to receive. In this case, the current-location mark on the display

must be corrected manually.

CAUTION:

The road map data is based on data stored on the HDD.

• In map-matching, alternative routes to reach the destination will be

shown and prioritized, after the road on which the vehicle is cur-

rently driven has been judged and the current-location mark has

been repositioned.

If there is an error in distance and/or direction, the alternative

routes will be shown in different order of priority, and the wrong

road can be avoided.

If two roads are running in parallel, they are of the same priority.

Therefore, the current-location mark may appear on either of them

alternately, depending on maneuvering of the steering wheel and

configuration of the road.

• Map-matching does not function correctly when the road on which

the vehicle is driving is new and not recorded on the HDD, or when

the 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-matching

function may find another road and position the current-location

mark on it. Then, when the correct road is detected, the current-

location mark may leap to it.

• Effective range for comparing the vehicle position and travel direc-

tion calculated by the distance and direction with the road data

read from the HDD is limited. Therefore, when there is an exces-

sive gap between the current vehicle position and the position on

the map, correction by map-matching is not possible.

GPS (GLOBAL POSITIONING SYSTEM)

GPS (Global Positioning System) has been developed and con-

trolled by the US Department of Defense. The system utilizes GPS

satellite (NAVSTAR), sending out radio waves while flying on an orbit

around the earth at the height of approx. 21,000 km (13,000 miles).

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 by using radio waves from four or more GPS satel-

lites (two-dimensional positioning).

Type

Advantage

Disadvantage

Gyroscope (angular velocity sensor)

• Can detect the vehicle's turning angle quite 

accurately.

• Direction errors may accumulate when the ve-

hicle is driven for long distances without stop-
ping.

GPS antenna (GPS information)

• Can detect the vehicle's travel direction 

(North/South/East/West).

• Correct direction cannot be detected when the 

vehicle speed is low.

NAVIGATION SYSTEM

Accuracy of the GPS will deteriorate under the following conditions.

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

changes.

• There may be an error of approximately 10 m (30 ft.) in position detected by three-dimensional positioning,

which is more accurate than two-dimensional positioning. The accuracy can be even lower depending on the

arrangement of the GPS satellites utilized for the positioning.

• Position detection is not possible when the 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.

• Position correction by GPS is not available while the vehicle is stopped.
