How can I reset the MMI system on an Audi A7?

I'm having trouble with my MMI system on my Audi A7. It seems to be frozen and I can't access any controls or settings. How can I reset it?

The MMI system can sometimes freeze due to a software glitch. Try resetting it by pressing and holding down the power button for 10 seconds. This should force a reboot and hopefully fix the issue.

If the power button method doesn't work, you can try disconnecting the car's battery for a few minutes and then reconnecting it. This will also reset the MMI system.

Sometimes, the issue could be with the MMI control unit itself. In this case, you may need to take your car to an Audi dealership for a professional diagnosis and repair.
