Fortuner audio system failure

I'm having a frustrating issue with the audio system in my 2011 Toyota Fortuner (gasoline engine). The whole thing just stopped working suddenly. No sound at all, not even static. I've checked the fuses, and they seem fine. I also noticed there's an error stored in the system memory, but I don't have the equipment to read it. Could it be a loose connection somewhere, or is my sound system completely fried?

It sounds like a defective display could indeed be the culprit, especially given the error code and complete lack of audio. Think of it like a central nervous system for your audio; if the 'brain' (display) is faulty, the 'body' (speakers, amp) won't function. Before tearing anything apart, do you recall any recent events that might have caused this, like a jump start or work on the electrical system?

Thanks for the quick reply! No jump starts or anything like that recently. The only thing I can think of is that it was a really hot day last week, and the car was sitting in the sun for a while. Could the heat have damaged the display unit?

Extreme heat could certainly exacerbate an existing weakness in the display, leading to failure. Given the symptoms and the stored error, a defective display module remains the most probable cause. I would strongly recommend having a qualified technician diagnose the specific error code. The repair, involving module replacement, could cost around 725€.

Thanks a lot for your help. I took it to a workshop, and you were spot on – it was the display unit. They replaced it, and now the sound system is working perfectly again. Cost me 725€, just as you predicted! I appreciate the advice.
