How to troubleshoot a faulty navigation screen in an Audi A6?

I constantly experience issues with the navigation screen in my Audi A6. It freezes, lags, and sometimes doesn't even turn on. What could be causing this and how can I fix it?

First, check if there are any software updates available for your navigation system. If that doesn't solve the issue, it could be a hardware problem. You might need to have it checked by a professional mechanic.

Sometimes, issues with the navigation screen can occur due to a faulty fuse. Check the fuse box and replace any blown fuses.
