Do yourself a favor and spend a few more dollars for an MP3 deck.. I personally went with one of the best deals around the JVC SX980 there are unlikely to be any others in that range that can compare to how complete it is.. does everything but pause and who really uses or needs that? You could switch to FM/AM anyway which works like pause and it will start where you left off when you switch back to MP3 mode..
BTW JVC SX-980 can be had for less than $185 if bought online and it's one of the best deals out there plus the deck isn't a bright silver that shouts "steal me now!" to any passerby it's got silver and red and blue highlights with a nice bright LCD, all in all it's a beautifully designed deck and if you're on a budget it's the best way to go till you can afford an Alpine or something in that range.. I bought mine
here for $183 shipped though you could get
SoundDomain.com to pricematch they have a % off type of pricematch and buy your harness and trim kit if needed there too..
The actual stereo installation is damn easy to do even if you are the dumbest sack of @%$& the world will ever see. All cars are the same for the most part.. I suggest you buy your deck online and maybe go to a site like SoundDomain.com to get where you can also buy a wiring harness for your car's model and year and a trim plate install kit if needed.. or you could go locally and check Walmart, Bestbuy, or auto supplies stores like Autozone for the install kits but don't buy the deck in a retail store, you get ripped off.. Buy new radio trim plate if required, if it's a DIN Mount (Check Crutchfield.com or the like to be sure) then it'll be very simple.. Wire the harness together with the one that comes with the stereo to the wiring harness that you bought to adapt to your car, just match the damn wires to each respective color twist them together and wrap them in electrical tape, or if you want you can solder or crimp them so it's a more bulletproof install. Remove stock or old stereo, Plug adapting harness into car and stereo. Mount the stereo's sleeve then push the deck through the sleeve till it locks and your done..
BTW you should probably disconnect the negative terminal on the battery or pull the radio's fuse so you don't accidently short something while wiring though that's unlikely with a wiring harness if you match up the wires correctly to begin with..
