How can I troubleshoot the Audi A7's infotainment system?

I've been having trouble with my Audi A7's infotainment system. It keeps freezing and some features don't work at all. What steps can I take to troubleshoot this issue?

First, try restarting the system by holding down the power button for 10 seconds. If that doesn't work, check for any software updates and make sure you have the latest version. You can also try resetting the system to factory settings.

Make sure all the cables and connections are secure and clean. Dust and debris can cause issues with the system. If the problem persists, it might be a hardware issue and you should take it to a certified Audi technician.

Check the fuse for the infotainment system. If it's blown, replace it and see if that solves the problem. If not, try disconnecting the battery for a few minutes and then reconnecting it.
