My bluetooth works ok up to a point, but I have a major issue, people can't hear me. I can hear them fine.

I replaced the mic with a garmin one, but same issue.

I tried updating the firmware, and also updated the bluetooth software, no joy.

 

Any ideas apart from getting the unit replaced by Pioneer?

I saw a person with the same issue here, but she had the unit replaced by pioneer:
