How do I troubleshoot the infotainment system in my Audi A7?

My Audi A7's infotainment system seems to be malfunctioning and I'm not sure how to fix it. Whenever I try to access certain features or settings, the screen freezes or shuts off completely. Any ideas on how to troubleshoot this issue?

First, try restarting the system by holding down the power button for 10 seconds. If that doesn't work, try disconnecting the car battery for a few minutes to reset the system. If the issue persists, it may be a software glitch, so consider updating the system or taking it to a dealership for further assistance.
