The following is included in each audio system:

A radio control located in the instrument panel (I/P)
A electronically tuned radio reception
The following six speakers:
- Four door mounted speakers
- Two quarter mounted speakers
A fixed antenna system (Hardtop)
A diversity (dual) antenna system (Coupe)
A power antenna system (Convertible)
A THEFTLOCK® radio theft-deterrent system

The Electronically Tuned Receiver (ETR) utilizes a programmer and synthesizer to provide optimum sound reproduction.

The ETR incorporates an electronic memory for preselected station and digital clock function. Reset the memory whenever the battery is disconnected.

Each system has a vacuum fluorescent (VF) display that coordinates with the other instrument panel (I/P) displays. The Body Control Module (BCM) controls the dimming of the display based on inputs from the I/P cluster which reads adjustments of the I/P cluster dimmer switch (rheostat). The Light Emitting Diode (LED) and the back lighting of the radio face is done with incandescent light powered directly by the I/P cluster dimmer switch (rheostat).
