All radio assemblies have electronic memory for selecting preset stations.

FM Stereo
All factory-equipped sound systems with an FM stereo radio perform the following functions when an FM stereo broadcast is received:
| • | The receiver will switch to stereo operation. |
| • | The indicator in the dial will light. |
Stereo operation occurs when the radio separates a stereo broadcast back into the following two channels:
| • | Left |
| • | Right |
Stereo sound is noticeably more realistic to the ear. Although FM is normally free from static, the following conditions may limit reception:
| • | The terrain |
| • | The atmospheric conditions |
| • | The strength of the station |
| • | The distance of the vehicle from the transmitter |
Buildings or other obstructions may cause any of the following conditions:
| • | Momentary static |
| • | Flutter |
| • | Station swapping |
If the reception is poor, tune to a stronger station.
Radio Assembly Controls
When the radio is turned on the following events will occur:
- The frequency will appear on the display for 5 seconds.
- The time will then appear on the display.
In order to recall the frequency push the RECALL button while the radio is turned on. Pushing the RECALL button will cause the frequency to appear on the display for 5 seconds.
When the ignition lock cylinder is in the LOCK or OFF position, the radio display will be blank. In order to display the time when the ignition lock cylinder is in the OFF or the LOCK position, perform one of the following actions:
| • | Push the upper knob |
| • | Push the RECALL button |
The time will display for 5 seconds. Then the display will become blank.
Radio Fixed Antenna Assembly
GM engineers designed the fixed antenna assembly in order to provide good radio omni-directional reception in moderate fringe areas.
