Many GM Oldsmobile Alero radios include a driver-specific radio settings function. The radio should recall the settings preferred by individual drivers. Other functionality includes an anti-theft system, and a speed compensation system that increases radio volume depending on road noise. Problems with Alero radios can be related to these features and also radio reception. These kinds of problems can be corrected by following some troubleshooting.
Switch the Speed Compensation Volume system on by pressing the button marked "SCV" if you can't hear the radio properly. Road noise may be blocking radio audio. SCV will compensate. Each button press toggles "Min," Med," and "Max" level settings.
Check that you are using the correct key fob if the radio hasn't remembered your personal settings. The system remembers the settings created by the user that last unlocked the car with a particular transmitter. So your settings won't be recalled if you use your spouse's key fob, for example.
Don't try to install an Alereo radio in another vehicle -- the radio won't work in it. The Alero radio incorporates a "Theftlock" system that memorizes part of the specific Alero's Vehicle Identification Number, or VIN, and the radio will fail to work in any other installation.
Eyeball the rear window antenna if radio reception is crackly, or stations that used to come-in don't anymore. The radio antenna is part of the rear window. Look for a thin wire and look for breaks that can indicate damage. Failure of the heated rear window and poor reception is a giveaway that there are electrical issues with the rear window. Check it visually and have it replaced if there's damage.
