How do you reset the MMI system on an Audi A4?

I recently encountered some technical issues with my Audi A4's MMI system and need to reset it. Can someone guide me on how to do this?

To reset the MMI system on an Audi A4, press the Nav button followed by the Setup button. Then, scroll to the bottom of the menu and select 'Reset MMI'. This will reset the system back to factory settings.

If the MMI system is not responding, you can perform a hard reset by simultaneously pressing the Menu, Nav, and Setup buttons for 10 seconds. This will force the system to restart and may resolve any technical issues.
