How do I reset the Audi A6 navigation system?

My Audi A6 navigation system has been having trouble lately and it's been showing me some incorrect routes. How can I reset the system and fix this issue?

Firstly, try resetting the navigation system by pressing and holding the power button for about 10 seconds. If that doesn't work, try disconnecting the car's battery for 10 minutes and then reconnecting it. If the issue persists, it might be worth getting it checked by a certified mechanic.

Another possible solution is to update the navigation system's maps and software. This can often fix any glitches or errors in the system. You can usually do this through the car's infotainment system or by visiting an Audi dealership.
