Section 47 (Audio System): Audio: Description

An audio system is standard factory-installed equipment on this model. Several combinations of radio receivers and speaker systems are offered as optional equipment on this model. The audio system uses an ignition switched control of battery current so that the system will only operate when the ignition switch is in the On or Accessory positions.

A optional navigation radio (RB1) is available on this vehicle. With this system, the operator has the option of choosing a street address, point of interest, trip itinerary and other features outlined in the operator's manual.

A Compact Disc (CD) changer with a ten-disc magazine, remote radio switches with six functions mounted to the backs of the steering wheel spokes, and a memory system that automatically stores and recalls up to twenty radio station presets (ten AM and ten FM) and the last station listened to for two drivers are optional factory-installed equipment on this model.

The audio system includes the following components:

• Antenna
• Compact disc changer
• Power amplifier (with premium speaker system only)
• Radio noise suppression components
• Radio receiver
• Remote radio switches
• Speakers

Certain functions and features of the audio system rely upon resources shared with other electronic modules in the vehicle over the Programmable Communications Interface (PCI) data bus network. The PCI data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, internal controller hardware, and component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many new feature capabilities. For diagnosis of these electronic modules or of the PCI data bus network, the use of a DRB III(R) scan tool and the proper Diagnostic Procedures manual are recommended.
