How do I reset the multimedia system in the Audi A6?

My Audi A6's multimedia system is frozen and I can't access any of the features. How can I reset it?

Try holding down the power button for at least 10 seconds, or until the system resets.

If the first solution doesn't work, you can also try disconnecting the car's battery for a few minutes and then reconnecting it.

If neither of those solutions work, it may be a more complex issue and you may need to bring your car to a certified Audi mechanic for further assistance.
