Corsa audio system unresponsive

I had a similar issue with my 2012 Skoda Octavia. The entire head unit died, and it was a defective display unit. Have you checked for faulty wiring behind the unit or speaker crackle? Inspect the car speakers for damage too.

Thanks. Any specific points to focus on when inspecting the wiring?

In my case, the power supply to the display was the problem. Inspect the main power connector and ground connections. Given the error memory and unresponsive system, it sounds like the display is defective. I'd suggest a workshop check.

Understood. I'll take it to a workshop. Seems the display is defective; the repair will be 725€.
