I highly doubt that VR (voice recognition) will work in a convertible with the top down. I can almost assure you of that. With the top up I'm not sure. Plus I get the sense that you have alot of road noise in a Miata.

However, that is the microphone that Hugo showed us and said they were reccomending (at least they were a few weeks ago - who knows at this point). I think it's a fantastic mic and I'm sure it's very receptive -- but it costs so damn much!
