No it will not. I got a USA-SPEC PATOY-15 iPod adapter unit for mine. It didn't have the AUX in on the HU. This $160 box is a little pricey, but it is worth it. It also requires you to pull the HU out, which takes about 1.5 hours. It took that long for me at least. Anyways, this little box plugs into the 12pin input behind the factory HU. This is for external CD changers. The box has software which controls the HU/Ipod. It tricks the HU into thinking its an external cd changer. It has a doc connector interface, digital quality, charges the iPod, displays text, and shuts the ipod off when you park. It also has an AUX input which you can play anything that has an stereo out (another ipod or dvd player, etc.). You install it, hit disc twice, and you have full ipod controls, with steering wheel controls. You also can control play list selection from the HU by naming your playlist TOYOTA1, TOYOTA2, etc. I mounted mine in the glove box, and routed the wires to my center console. It is a nice setup and i think it's worth every penny spent. But if i were you I would just get the double sided stereo cord (walmart, target, best but) and enjoy my music that way.
