JHM2K and I have been working for quite sometime on these. Now you can talk to your fellow Crossfire driver whilst driving. You're probably asking yourself what the plus side of this devise is.... Well I can't really think of one, exclusivity? A way to talk to another driver without being pulled over by the local PD for talking on your phone?

Listen, we've worked really hard on this, and would like to recoupe our r&d money on it. So please send me money via paypal and we'll call it even
Cheers,
Nick
