What is the virtual cockpit in an Audi A4 and how does it work?

I am interested in buying an Audi A4 and I've heard about the virtual cockpit. What exactly is it and how does it function?

The virtual cockpit in an Audi A4 is a fully digital information display behind the steering wheel. It replaces traditional analog gauges and provides driver with customizable, high-resolution graphics and information such as navigation, media, and vehicle diagnostics.

Think of the virtual cockpit as a digital hub for all your driving needs. With a few clicks of a button, you can switch between different displays and have essential information right in front of you at all times.
