C30 Microphone Failure

I'm experiencing a complete failure of the hands-free microphone system in my 2009 Volvo C30 diesel. Telephony is no longer possible, and an error is stored. With 41826 km, is it wear and tear, or something more? Has anyone encountered this before? I suspect the infotainment system.

A complete microphone failure in the C30 is unusual. It sounds like a deeper problem than a simple setting. Have you checked the fuse box? Also, has the Bluetooth connection been stable?

I did check the fuses, and all appear to be in order. The Bluetooth connection has been rock solid up until this microphone issue. Could a software glitch within the infotainment system be the culprit, perhaps needing a system reset?

Given that the fuses are fine and the Bluetooth connection was stable before, a software issue is less likely, though still possible. If the hardware itself is broken it would also render it useless. Diagnosing microphone problems is tricky without the proper tools. It's best to consult with a workshop.

A trip to the workshop was unavoidable. The diagnosis confirmed a defective infotainment system, resulting in a repair cost of 815€.
