Will changing the battery on your Mini Cooper affect radio?
Changing the battery in your Mini Cooper may temporarily interrupt power to the radio, causing it to lose its settings or require a security code to be entered. After the battery has been replaced, you may need to re-tune your radio stations and/or enter the security code to restore functionality. Consult your vehicle's owner's manual or contact your local Mini dealer for specific instructions on how to reset your radio after a battery change.
