I found a Neucleus NC-X2i and a Toyota 1998-2006 wiring harness on clearance at a Canadian tire for $55, regular $135. This is similar to the DICE pod unit that they sell in the Priuschat shop. The application guide does not mention the Prius but it works anyway. I have only tried it with a non ipod mp3 player though. Now I'll have to find a good deal on an ipod! It's like this unit.NEUCLEUS IPOD ADAPTER BY AMERICAN INTERNATIONAL (TOYOTA NC-TA95T)::IPOD DIRECT COMPATIBLE AUX ADAPTERS::AUX AND IPOD ADAPTERS::OEM Factory Aux Ipod Adapters & Changers::AUTOTOYS
