How do I reset the navigation system in my Audi A2?

I accidentally messed up the settings on my navigation system and now it's not working properly. How can I reset it back to its default settings?

To reset the navigation system in an Audi A2, press and hold the Radio and Setup buttons for about 10 seconds, until the display resets. Then, go to the Navigation menu and select 'Reset'. This should solve any issues with your system.

If the above method doesn't work, you can also try unplugging the car battery for a few minutes and then plugging it back in. This may help reset the navigation system.
