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.
They're always good for a 'no surprises' install as they will let you know
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.
