How do I troubleshoot the MMI system in an Audi A2?

I'm having trouble with my MMI system in my Audi A2. It keeps freezing and I can't access any of the features like navigation or audio. What steps should I take to troubleshoot and fix this issue?

First, try restarting the MMI system by holding down the power button for 10 seconds. If that doesn't work, check the fuse for the MMI system and replace if necessary. If the issue still persists, it may be a software problem and you should take your car to a dealership for further diagnostics and potential updates.
