How to reset the MMI system in my Audi Q5?

I recently purchased a used Audi Q5 and the MMI system seems to be frozen. What is the best way to reset it?

To reset the MMI system in your Audi Q5, start by pressing and holding the MENU and CAR buttons simultaneously for 5 seconds. This should force the system to reboot and clear any glitches. If that does not work, you can also try disconnecting the car's battery for a few minutes and then reconnecting it. Sometimes this will also reset the system.

One thing to try before resetting the MMI system is to check for any software updates. Audi occasionally releases updates that can fix bugs and improve performance. You can check for updates by going to the Settings menu in your MMI system and selecting 'Software Updates'.
