How to reset the MMI system in the Audi A6

I am having some issues with the MMI system in my Audi A6 and I want to reset it to see if it resolves the issue. How can I reset the MMI system on my Audi A6?

To reset the MMI system in your Audi A6, press and hold the MENU button on the MMI control panel for about 5-10 seconds. This will reboot the system and should resolve any minor issues you may be experiencing.

If that doesn't work, try disconnecting the car's battery for about 20 minutes and then reconnecting it. This will also reset the MMI system. Make sure to have the radio code handy before doing this.
