Highlander Hybrid Microphone Failure

Hey, I'm having trouble with the hands-free microphone in my 2020 Toyota Highlander Hybrid. Bluetooth calls aren't working, and there's an error code. I think it might be the infotainment system. It has 127471 km on it. Anyone else seen this?

The hands-free microphone in a 2020 Toyota Highlander Hybrid stopped working, affecting Bluetooth calls and speech recognition. The issue was suspected to be related to the infotainment system. After troubleshooting, including a factory reset and checking Bluetooth settings, the problem persisted. A professional diagnosis confirmed a faulty infotainment system, which required replacement.

Sounds like a short circuit, which can be tricky to find without the right tools. Is the speech recognition also not working? Have you tried resetting the infotainment system or checking the Bluetooth settings? Also, did anything happen before it failed, like a software installation or any repair?

Thanks! Yeah, speech recognition is dead too. I did a factory reset and checked the Bluetooth a bunch of times, but no luck. Nothing was done to it right before the mic stopped working.

Got it. Since both the phone and speech recognition aren't working after a reset, and nothing obvious triggered it, it probably is a problem inside the infotainment unit. You've probably done all you can. I'd suggest getting it checked out by a pro to avoid making it worse.

Thanks for the help. Took it to Toyota, and they said it was a bad infotainment system, just like I thought. Cost 815€ to replace.
