How to troubleshoot a malfunctioning Audi A5 infotainment system?

My Audi A5's infotainment system keeps freezing and I can't access any of the controls. What should I do?

First, try restarting the infotainment system by holding down the power button for 10 seconds. If that doesn't work, check if there are any software updates available for your system. You can do this by going to the settings menu and selecting 'software update'. If there are no updates available, you may need to bring your Audi to a certified mechanic for further diagnosis.
