How do I update the navigation system in my Audi A8?

I recently purchased a used Audi A8 and I'm not sure how to update the navigation system. Can someone provide me with step-by-step instructions?

First, make sure your car is connected to a Wi-Fi network. Then, go to the media menu and select 'update navigation maps'. The system will check for any available updates and prompt you to download them.

If your car is not connected to Wi-Fi, you can also download updates using a USB drive. Simply go to the Audi website and download the update file onto the USB. Then, insert the USB into your car's media interface and follow the on-screen prompts to update the navigation system.

I suggest contacting your local Audi dealership for assistance with updating your navigation system. They may have more specific instructions for your particular model and can also check if any updates are available.
