Excursion audio system failure

That's a bummer. I had a similar issue with my old Renault Megane, though it was just speaker crackle and intermittent dashboard control failure, not a completely dead system. Did you check the fuses?

Yes, I checked the fuses. All seem fine. Could it really be just the head unit causing the whole system to fail like this?

It's possible. In my Renault, a faulty head unit was indeed the culprit. I tried everything before taking it to a workshop. They confirmed it and replaced the unit. Honestly, with all those electronics, it's tough to diagnose without the proper tools. Could be worth a visit to a shop.

I appreciate the input. I took it to a shop and they confirmed the display was defective, as I suspected. Repair cost 725€. All sorted now.
