How does the Audi A3 virtual cockpit work?

I've heard about the virtual cockpit in the Audi A3, but I'm not sure how it actually works. Can someone explain it in more detail?

The Audi A3 virtual cockpit is a fully digital and customizable instrument cluster that replaces traditional analog gauges. It displays all of your important driving information in high-resolution and can also incorporate navigation and media displays. To navigate through the various screens, simply use the buttons on your steering wheel.

Think of the Audi A3 virtual cockpit as a digital dashboard that gives you complete control and access to all of your vehicle's settings and information. It also has advanced features like Google Earth integration and 3D maps. You can personalize the information displayed for each driving mode and also switch between classic and infotainment views.
