It's actually really simple to swap stereos in. the price they are quoting you is insane. Stereo shops in SC are around 40 bucks for install, 15 for harness and double din kit. Incidentally what stereo did you buy for yours? If you don't fancy trying it on your own, Best Buy is a pretty decent bet. When I bought my Pathfinder, it took about 30 minutes to swap in my Pioneer double Din Nav. If you do a quick search of Crutchfield, they even give you the step by step on how to do it yourself. Really the parts are about 15 to 20 bucks. A good way for you to save yourself some cash, and learn a little more about the truck. YMMV.
