How do I troubleshoot the MMI navigation system in my Audi A8?

I am having trouble with my MMI navigation system in my Audi A8. It keeps freezing and giving me incorrect directions. What steps can I take to troubleshoot this issue?

First, try resetting the MMI system by holding down the power button for 10 seconds. If that doesn't work, check for any software updates that may fix the issue.

You can also try disconnecting the battery for a few minutes and reconnecting it to reset the system. If this doesn't work, it may be a hardware issue and you should bring it to a certified Audi technician.
