Why is the MMI screen on my Audi A6 not turning on?

I have recently noticed that the MMI screen on my Audi A6 is not turning on. The rest of the car seems to be functioning normally but I cannot access any of the car's features through the screen. What could be causing this issue and how can I fix it?

Samantha: Have you tried resetting the MMI system by holding down the power button for 10 seconds? If that doesn't work, it could be a problem with the fuse or a faulty connection. I recommend taking it to a certified mechanic for further diagnosis and repair.

John Smith: I had a similar issue with my Audi A6. It turned out to be a software glitch and was easily fixed by updating the MMI system. You can do this yourself by downloading the update from the Audi website and following the instructions.
