Just purchased a 2014 Boxster S and have been able to connect my android 4.3 to my PCM via bluetooth. When I receive calls, I can hear the party fine, but they only hear a very muffled dialogue from me. I have looked and can not find where the microphone is located in this vehicle. I called the dealership and was told that the bluetooth connectivity and reliability has been an issue with Porsche and that they will get back to me. All other bluetooth features work great.

My question is:
1. Has anyone else had this issue and was able to resolve it?
2. Where is the bluetooth microphone located?

Thank you for your help
