< SYSTEM DESCRIPTION >

[BOSE AUDIO WITH NAVIGATION]

AUDIO SYSTEM

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:0000000007347816

NOTE:

Refer to NAVIGATION 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.
