This is a great set-up. I have been running it for a month now and it gives you nice flexibility between in town running around and max open road driving with minimal button pushing. I do wish though a setting of more than 30 seconds could be set. As most traffic lights are longer than 30 seconds sitting there at a light means you are going to have to press the mute one more time. I would like it if at any time in little L under 4 dots you stay in a muted state.
