you need alot of extras like the jbl amp and there is a wire harness that you can get from toyota to plug it in. if you eventually want to get the navi to work you'll need the antenna and map cd. theres a link in this site with step by step instructions and pics. sorry i dont know it off hand but i know i've seen it. i had also purchased a stock navi unit, but after seeing what u have to go through to install in in a non jbl---i sold it. check out the the boyo avn unit it sells for around $600 and you get alot of bang for your buck.
