Just wondering how good of or what kind of mic specifically is needed to be able to use the voice command aspect of streetdeck. I see the mic that's sold in the mp3car store but it seems a little high priced for my budget. Hoping there's something I can pick up under $40-50 that would work well enough.

Also, I'm just wondering exactly what you can do with a mic in streetdeck. I searched microphone in the streetdeck forum and read all the threads that came up but it seems like not very many people are using mics with streetdeck. Just wondering if it allows you to...for example....name an artist or album and have that come up or if in navigation you can spell out an address and have it create a route to that destination. If not, what kinds of useful things can the mic do in streetdeck?
