No issues for me. I’m always told my voice comes in clear. I am using aftermarket radio though.i do find that Siri’s voice recognition is not as good in the car when it is using the car’s microphones. You can tell when it is happening in our older car because it switches from radio to Bluetooth mode when you invoke Siri, even from the phone. The car’s microphones don’t have the same noise reduction that the phone’s do.
