Why is the MMI display on my Audi A5 frozen and how can I fix it?

I was driving my Audi A5 and suddenly the MMI display froze. I couldn't change the radio station or use the navigation. What could be the cause of this issue and how can I resolve it?

It is possible that the software in your Audi A5's MMI system has crashed. Try restarting your vehicle and if that doesn't work, try resetting the MMI system by holding down the MENU button for 10 seconds. If the issue persists, it may require a software update at the dealership.

It is also possible that there is a faulty connection in the display. Check all the cables and connections to ensure they are secure. If the issue is still not resolved, it may need to be looked at by a mechanic or technician.

Another potential cause could be a defective display unit itself. This can happen from wear and tear over time. If you have warranty on your vehicle, it may be covered for replacement or repair. Otherwise, it is best to consult a professional.
