Like I said, the local shop sold it to me and installed it for the same price Crutchfield was selling it for. I had them do it because it was free and I'm not the most mechanically inclined.
Do yourself a favor and go here
. Put in your info including the stereo you currently have and see what Crutchfield has available for your car, in the price range you want to spend, with the features you want. Then it comes down to the best manufacturers, single-DIN vs. double-DIN, just stereo vs. DVD receiver, etc.
