How do I troubleshoot the navigation system on my Audi A5?

I recently purchased a used Audi A5 and the navigation system doesn't seem to be working properly. The maps are not loading correctly and it keeps freezing. What could be the issue and how can I fix it?

First, try resetting the navigation system by holding down the power button for 10 seconds. If that doesn't work, it could be a problem with the software. Try updating the system or contacting your local Audi dealership for further assistance.

Make sure the GPS antenna is properly connected and not obstructed. If it is, try disconnecting and reconnecting it. If all else fails, it could be a hardware issue and you may need to get it checked by a professional.
