How can I troubleshoot the multimedia system in my Audi A7?

I recently purchased a used Audi A7, and I'm having trouble with the multimedia system. It sometimes freezes or doesn't respond to my inputs. Is there a way to troubleshoot and fix this issue?

First, try restarting the system by holding down the power button for 10 seconds. If that doesn't work, try disconnecting the battery for a few minutes and then reconnecting it. Sometimes this can help reset the system.

Another potential solution is to perform a software update on the multimedia system. Often, manufacturers release updates to fix bugs and improve performance. Check the Audi website for instructions on how to update the system.
