What is Audi MMI and how does it work in the Audi A3?

I recently purchased a new Audi A3 and noticed it came equipped with Audi MMI. But I'm not sure exactly what it is and how to use it. Can someone explain it to me?

Audi MMI stands for Multimedia Interface and it's essentially a central control system for all the advanced features in your Audi A3. You can control the navigation, music, phone, and other functions through its user-friendly interface.

To use the Audi MMI in your A3, you can use the central controller knob or touchpad, which is located on the center console. You can also use voice commands to interact with the system.
