I just don't understand why third party car audio companies don't automatically include an AUX input on everything except the super-cost-conscious lowest-end units. This Pioneer, for example, has pretty much all the features you could want, and even looks nice in the Crossfire dash. But it just bugs me to no end to pay for a good third-party head unit and still have to attach an iPod (or other removable, external source) via the antenna lead.

I notice that this unit will control Pioneer CD changers. Does anyone know enough about car audio to know if that means there's an audio-in somewhere that could be used? Perhaps it's part of a proprietary connector that would also carry the control information for the Pioneer changer if you were using one?

Cheers,
