Maybe I'm the only person on the planet that sees not only the opportunity for this, but even a need for it when you've spent $500 (CDN) on a 40gig mp3 player.... A simple way to hook it up to your car deck and use it as part of your integrated car system. There are relatively easy ways of achieving this; using Kenwood decks that support it's new Music Keg you could build an adapter to go from that connector into the Karma - and the entire framework is already there and ready for you; maybe after a small Karma firmware update. Alpine has their iPod connection system that does the same sorta thing - but who wants to buy a damned iPod?
Is this just a pipe dream and I'm goin gto have to stick to "CD 1 Track 1" or "AUX" and let the Karma play through that? Eugh.
