what you need is the install kit consisting of the harness and the pieces you need to install the radio, you can buy both cheaply over ebay
it is an easy install really, it works the same for every car really, just match the same color wires up and your set, pretty easy, but look at another guide if you become confused
its the first generation. Ive installed decks before, i was just wondering if i need to buy a dash kit or whether i can just use the one thats in there. It looks like the stock radio is single din
