SM3 audio system fault

My 2020 Renault SM3 (electric engine) has developed an audio system fault at 140450 km. The system is completely dead, and the error memory shows a fault. Suspect the display is defective.

I had a similar issue with my SM3. Check the head unit connections first, sometimes a loose wire can cause the whole thing to shut down. Also, any weird crackling from the speakers before it went silent?

No crackling, just silence. Where exactly are the head unit connections located? Are they easily accessible, or do I need special tools to get to them?

It's behind the dashboard, which isn't easy to access. It sounds like your issue might be more serious if there was no warning. I'd suggest taking it to a workshop. I ended up paying 725€ for a new display.

Thanks for the info. Sounds like it's beyond my capabilities. I'll book it in for a diagnosis and repair.
