How do I reset the MMI in my Audi A7?

I recently noticed that my MMI in my Audi A7 is acting up. How can I reset it to its factory settings?

To reset the MMI in your Audi A7, first turn off your engine and remove the key from the ignition. Then, press and hold the MENU, CAR and BACK buttons simultaneously for 10 seconds. This will reboot the system and return it to its factory settings.

Another way to reset the MMI is by disconnecting the car battery for a few minutes and then reconnecting it. This will also reset the system. However, make sure to have your radio code handy before attempting this method.
