Do you have a recent model Toyota with Entune? Did your microphone and/or wifi suddenly stop working? The wifi app doesn't work. You can make and receive calls and can hear the other party but they can't hear you. Voice commands don't work anymore.
The issue is likely the DCM. You can verify it by looking at the display and seeing the DCM greyed out even when bluetooth is connected. Also, the SOS in the ceiling doesn't have a green light.
The fix is simple. Open the hood. Open the fuse box on the right. Pull out and put back the DCM fuse.
