Purchase the complete set (three volumes) of repair/service manuals for the 05 Prius. Will work for the 04 and 06 (minor changes to Navigation software). Selling for $225 delivered in the 48 states. Great reference to help you understand the inner working of the Prius. It will help you in explaining and overseeing work performed by the dealerships. Why bother trying to download and then trying to put it all together. This is an easy to use set of books. My email is drmanny3@cox.net
