Radio/Stereo: Description and Operation

AUDIO
Several combinations of radio receivers and speaker systems are offered as optional equipment. The audio system uses an ignition switched source of battery current so that the system will only operate when the ignition switch is in the ON or Accessory positions.

The audio system includes the following components:
- Antenna
- CD Changer
- Power amplifier (with premium speaker system only)
- Radio noise suppression components
- Radio receiver
- Speakers

The vehicle has two speaker systems:

Standard Speaker System
- Two instrument panel mounted speakers (JR 27)
- Two door speakers
- Two rear shelf panel speakers (JR 41)
- Two rear quarter trim panel speakers (JR 27)
- Separate top-up vs top-down equalization curves in the radio (JR 27)

Premium Gold Amplified Speaker System
- Amplifier mounted under the front passenger seat
- 150 watt Amplifier with separate top-up vs. top- down equalization curves (JR27)
- Two instrument panel speakers
- Two door speakers
- Two rear shelf panel speakers (JR 41)
- Two rear quarter trim panel speakers (JR 27)

See the owner's manual in the vehicle glove box for more information on the features, use and operation of each of the available audio systems.

CD CHANGER
The 4 Disc In-Dash CD Changer (if equipped) is located in the instrument panel below the radio. The remote changer does not use a cartridge or magazine for the CD's. Up to 4 CD's can be directly loaded into this unit, one at a time.

Due to its compact design, the CD changer can carry out only one operation at a time. For example, you can not load a new disc while playing another at the same time. Each operation happens sequentially.

The radio unit provides control over all features of the CD changer with the exception of the CD load and eject functions, which are controlled by buttons located on the front of the CD changer. All features you would expect, such as Disc Up/Down, Track Up/Down, Random and Scan are controlled by the radio, which also displays all relevant CD changer information on the radio display.

On JR27 models, the CD changer will not operate with the ignition in the OFF position. With the ignition OFF, CD's can not be removed from the changer.

The CD changer contains a Load/Eject button and an indicator LED for each of the four disc positions as well as an illuminated disc opening. The individual LED indicates whether a CD is currently loaded or ready to load in that particular chamber of the CD changer. Pressing the individual Load/Eject button for a particular chamber will eject a disc currently present in that chamber. If the chamber is currently empty actuating the Load/Eject button will position that chamber to receive and load a new disc in that chamber.

Two wires connected to each speaker, one feed circuit (+) and one return circuit (-), allow the audio output signal electrical current to flow through the voice coil. For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
