Each audio system consists of the following components:

    • The radio
    • Four speakers
    • The antenna

The following audio systems are available:

    • Delco® AM/FM Stereo Radio with clock
    • Delco® AM/FM Stereo Radio Cassette Player with clock
    • Delco® AM/FM Stereo Radio Compact Disc Player with clock

The ignition switch must be in the ACC or ON positions in order to operate any of the sound systems. The 2 front speakers are located on the front doors behind the trim panels. The 2 rear speakers are located in one of the following positions:

    • Behind the rear quarter trim panel (2-door models)
    • On the rear window-to-rear seatback shelf (4-door models)

Notice: All GM factory equipped audio systems have ungrounded speakers. Installing after-market tape players, citizen band radios or other units which use the factory speakers may damage the audio system or impair the operation of the after-market unit.

FM Radio Reception

The FM tuner operates on a band from 87.7-107.9 MHz. Optimum FM radio reception range is usually limited to a maximum of 16-64 kilometers (10-40 miles). The range depends upon the following conditions:

    • The terrain
    • The atmospheric conditions
    • The station power
    • The antenna height
    • The distance from the transmitter.

Signal flutter or noise may result from tall buildings, hills, or from other objects. You may eliminate this problem by tuning to a stronger station.

AM Radio Reception

The AM tuner operates on a band from 530-1710 kHz.

The range of most AM stations is greater than FM, especially at night. The longer range may cause stations to interfere with each other. AM reception is also subject to noise interference from storms and power lines. Reduce the treble in order to help reduce the noise.
