How do I troubleshoot a navigation system in my Audi?

I recently purchased an Audi and the navigation system is not functioning properly. It often gives incorrect directions and takes a long time to load. How can I fix this issue?

First, try resetting the navigation system by pressing and holding the power button for 10 seconds. If this doesn't work, check for any software updates and install them. If the issue persists, you may need to bring your car to an Audi dealership for further assistance.

Make sure that the GPS antenna is properly connected and not obstructed by any objects on your car. You can also try recalibrating the navigation system by going to the settings menu and selecting the recalibration option.
