How can I reset my MMI system in Audi A3?

I am having issues with my Multi Media Interface (MMI) system in my Audi A3 and need to reset it. Can anyone provide step-by-step instructions?

To reset the MMI system in your Audi A3, start by pressing the 'Menu' button on the main control panel. Then, go to 'Setup', followed by 'Settings', and select 'System Reset'. This will bring up the option to reset the MMI. Keep in mind that this will erase all personal settings and data stored in the system, so proceed with caution.

If the above method does not work, you can try resetting the MMI system by unplugging the car battery for about 15 minutes. This will allow the system to completely power down and reset itself. However, make sure you have any necessary codes or PINs for your device before doing this.
