This microphone works fine with my NIX-8100 however it does a poor job of isolating my voice for voice commands. People say I sound clear on the telephone, but the car still messes up all of my voice commands. Basically, android/my phone get my commands perfect when I use the phone mic, but when I use the car mic it has less than a 50% success.

3 Stars for matching the spec/radio.
-2 Stars for doing a terrible job at being a mic
