How do you reset my 2006 Grand Prix radio settings?

To reset the radio settings in your 2006 Pontiac Grand Prix, start by turning the ignition to the "On" position without starting the engine. Then, press and hold the "Power" button on the radio for about 10 seconds until the display resets. If your radio has a "Reset" or "Factory Settings" button, you can also press that. Finally, consult your owner's manual for specific instructions if needed.
