I know I am not the only one with this issue, but I wanted to know if anyone was able to find a fix for the external mic not working when using Siri or making or receiving phone calls. The mic works when I am connected to bluetooth, but CarPlay disconnects your phone from bluetooth, and I want to use CarPlay. Any help at all is appreciate.

This is working for me.  HOWEVER, Siri is spotty.  Sometimes it works and sometimes it doesn't.  I don't think that piece of it is related to the microphone, though.  Maybe she's mad at me like when you cuss at her?

I fight with Siri to work too sometimes, you have to time it just right
