I think you would have better luck plugging this functionality into 3rd party audio vendors hardware. Think about how many people already trust names like Sony, Alpine, etc. Most consumers won't throw that kind of money around unless the equipment is backed by a manufatures warranty and can plug into other components in their car audio system. It's a great idea, now all it needs is a BIG NAME backing it.
