Maybe...although I was told by both Circuit City and and very reputable pro shop, that what I did in 30 min. myself was impossible. I think that (what you said kinda indirectly) the people are the key...if you know someone that has had quality work done, get the name and location of that installer. Ask around for as many referrals as you can get, and go by that, not the name of the shop.

Oh, and to get back tothe original question, this Install section has everything you need to learn how to do it yourself, there is everything from Pathfinders to Ferrari's in here.
