Koleos Audio System Failure

Whoa, bummer! No sound at all? Does that include the parking sensor beeps and turn signal sounds? Have you tried messing with the dashboard controls, like the volume knob? Maybe it's just stuck on mute or something silly? Static noise? Speaker crackle?

Yeah, completely silent – parking sensors, everything. The dashboard controls don't do anything, and I've checked the obvious mute settings. No static noise or crackle before it went silent, just poof gone. What do you think?

Hmm, that sounds more serious than just a mute button snafu. Given it's affecting everything and there's an error code, and the dashboard controls don't work, I'd guess the display itself might be defective, potentially the source. I heard the repair could cost around 725€. Honestly, you're probably best off taking it to a workshop.

Ugh, that's what I was afraid of. Thanks for the info; looks like a trip to the shop is in order. I will post what they find!
