I took it to the dealership again today on monday. He wasn't sure what caused it. He reflashed the entire system and updated it. Afterwards when it still wasn't working he said he did a hard reset on the entire thing after disconnecting the microphone. Tried it again and it didn't work. Then for good measure he said he disconnected the microphone one more time and did a hard reset....IT WORKS! I was able to make a call and the person said they heard me loud and clear. The call quality was great. Nice, loud and crisp. They said if it happens again since they're still not sure what caused it expect to drop it off for the entire day while they call all their service departments to figure out solutions from their techs...I hope it doesn't come to that! But i'm stoked it works, its been hard using a cell phone mounted to the dash with the cell speaker since it's not so loud.
