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.
