A week ago I could receive calls but the caller couldn't hear me. I also notice my navigation system did not work. Voice commands were not recognized. I replaced the roof top fin antenna and the microphone thinking there was a water leak that caused the problem. Voice communication, GPS and Onstar is still not working. Is there a fuse in the interior panel i can check to see if power source is causing it? I want to check the fuse before spending money on a new communication module

I've got the same problem. My mic just stopped working one day. I can hear people when they call but they can't hear me. I also tried voice commands. No voice recognized. Did the bluetooth microphone just stop working? Should I replace the mic or is there something else?
