Okay, so background info. Alpine electronics has just released a new multimedia headunit called the iva-w505. Alot of you who are into car electronics probably know that Alpine has always had optical toslink out on their h/u's. Well, this year they've changed it. Right now no one knows for sure or not if this new connection is proprietary (meaning that I'd need a special cable/converter box made by Alpine) or if there's a cable out that has this connector on one end, and toslink on the other.
Picture is below. The digital jack is the copper one with 4 pins, in the lower RH side w/ the two white plugs adjacent.

Anyone have any ideas what this could be? As I said, this is new, and this could be proprietary. Just thought I'd ask here to see if anyone may know of a cable like this.
