How do you turn off the radio in your BMW 320i 2001 model?

To turn off the radio in a 2001 BMW 320i, simply press the power button on the radio or stereo unit. If your car has a separate volume knob, turning it counterclockwise to the minimum can also turn off the sound. Additionally, you can try pressing the "Media" or "CD" button to switch off the radio functions. If the radio is integrated into the dashboard, it may turn off automatically when the ignition is turned off.
