How to fix the malfunctioning multimedia interface in Audi A1?

My multimedia interface in my Audi A1 has stopped working. The screen is black and does not respond to any buttons. How do I fix this?

You can try resetting the interface by pressing and holding the power button for 10 seconds. If that doesn't work, it may be a hardware issue and you should bring it to a certified Audi technician.

Make sure all the cables connecting to the interface are securely connected and not damaged. If that doesn't solve the issue, you may need to replace the interface.

Try updating the software of the interface through the Audi website. If the problem persists, it may be a compatibility issue with your device.
