Lexus SC Microphone Failure

Hey, I have a 2007 Lexus SC with a gasoline engine, and the hands-free microphone has stopped working. Telephony is no longer possible and there's an error stored in the error memory. I've checked the volume control and wireless connection, but no luck. Any ideas?

I have a Lexus SC too, and I had a similar problem with the microphone. Was your sound quality also bad before it completely failed?

Sound quality was fine. It just cut out completely. Is the likely cause also the infotainment system?

Yeah, sounds like the infotainment system. I'd suggest taking it to a workshop. My repair cost was 815€.

Thanks for the advice. I'll take it in. Turns out it was the infotainment system after all. Cost me 815€ too to get it fixed.
