How do I reset the navigation system on my Audi A8?

I am having trouble with my navigation system on my Audi A8. It seems to be frozen and not responding to any commands. How can I reset it?

First, try disconnecting the battery for a few minutes and then reconnecting it. This can often reset any issues with the navigation system.

If that doesn't work, you can also check the fuse for the navigation system. If it is blown, replace it and see if that solves the issue.

Another option is to perform a factory reset on the navigation system. This will erase all saved data, so make sure you have a backup before attempting this.
