If you are not talking about a powered cradle, and just something to hold your iPod while you run your own cables to the AUX and power inputs, then there is a foam iPod holder that fits in your cupholder. The best way for me to describe it would be like one of those foam holders for a soda/beer can, but with some ridges on the top edge where you iPod sits. When my TCH was at the dealer, they gave me a Scion tC as a loaner and it had one of these things in the cup holder, and at first I could not figure out what it was! Anyway, I've since seen it elsewhere in use, and it does a great job for it's intended use. No squeaks or noises because it's made of soft foam, there's no shifting or sliding around, and it does not take more space than a single cup holder. You can find them on EBay, if you don't find a Toyota-branded accessory, do a search for "Scion ipod".
