Check out Crutchfield. They have a "what fits my car" service where
you select make, model and year and they show you what fits your car.
Prices are a bit high but no tax and low shipping along with detailed
instructions and included harness make up for the difference.
everything you need (adapters, cables, tools) before you start. They also
have really great 1-800 support to help you if you get stuck.
I would compare prices with the local superstores before you buy however, as
they sometimes run 'free install' specials that are hard to beat.
