What is Audi A1's MMI system and how does it work?

I'm considering buying an Audi A1 but I'm not familiar with their MMI system. Can someone please explain what it is and how it works?

The Audi A1's MMI system stands for Multi-Media Interface, it's a centralized control panel that allows you to access and control various features of your car such as navigation, audio, and phone. When you choose a function, the MMI screen will display the relevant information and you can use the dial or buttons to navigate and control it.
