What Does the MMI System in the Audi A4 Do?

I recently purchased a new Audi A4, and I'm confused about what the MMI system is actually used for. Can you explain its purpose and features?

The MMI system in the Audi A4 is essentially a central hub for all your car's functions and settings. It controls everything from the navigation and entertainment systems to the air conditioning and phone connectivity.

Being fairly unfamiliar with the MMI system myself, I've found it useful to read the owner's manual or watch tutorials online. This will give you a better understanding of the specific features and how to access them.
