OK, I know it is rubbish and talking by phone in the roadster is meaningless. But not for me. frequently I have emergency service and I m called on my cell phone when I m in the car. Everything "worked as expected", but some months ago, I got this problem: The phone makes a connection and I can hear the caller ( or the person I have called ), but they do not hear me. They don't hear anything ( no noise ). I m listening music by my phone and bluetooth without any problems. After several months of wait a Tesla ranger came by and said the microphone is broken and replaced it and told me that now it works. When I got from work ( in the Renault Zoe ) and tested it, it didn't. I took the phone of my wife: Same problem. The other side does not hear anything... Any ideas?
