How to reset the MMI system in an Audi?

I am having trouble with my MMI system in my Audi. It seems to be frozen and I can't use any of the controls. How can I reset it?

First, try holding down the power button for 10-15 seconds until the system restarts. If that doesn't work, try disconnecting the car's battery for a few minutes and then reconnecting it. If the issue persists, you may need to take it to a mechanic for further assistance.

I had the same problem with my Audi and I found that resetting the MMI system using VAG-COM or VCDS software was the most effective solution. You can also try removing any connected devices, like a phone or USB, to see if that helps.
