How to troubleshoot the MMI system in my Audi A3?

I've been having issues with the MMI system in my Audi A3. It keeps freezing and doesn't respond to any of my commands. What steps should I take to troubleshoot this problem?

First, try restarting the MMI system by holding down the power button for 10 seconds. If that doesn't work, check for any software updates for the MMI system. If there are updates available, make sure to install them. If the issue persists, you may need to bring your car to a dealership for further diagnostics and potential repairs.

Have you tried resetting the MMI system by pressing the MENU, SELECT, and RETURN buttons at the same time? If that doesn't work, it could be a hardware issue and you should have it checked by a professional.
