I am working on a deal with a guy to buy the Scion iPod-capable HU and he has it advertised as factory sealed. Does anyone know if it comes in the box with all necessary wires to do the total install - that is, upgrade from the stock HU? I called Josh at TRD and he didn't think it did, but was not sure. Any help, in quck fashion if possible, would be great.

I ask here because the seller is a little skittish and I've bargained hard up to this point!
