Simple replacement. I've done it on everything as i worked in a car audio shop. Depending on set up, all you need to do is pull on the dash pace-plate and it will pop out. If you have a cup holder in the dash you should pull it out as it will make it easier. Make sure the wheel tilt is all thew way down. Move shifter as needed to provide clearence. Once the dash is out and you've disconnected the wiring bundles(for cargo light if you've got it, and for headlight/dimmer switch) its all down hill. All you have to do is depress the two tabs on either side of the stock deck and pull out. To install a new deck, you'll need to have the conversion/fit plate, and an antenna adaptor. GM antenna leads are smaller than others. A wiring harness is nice so you just have to plug it in, but you can hard wire it and save about 12 bucks. If you do hardwire it, you can find most wiring codes at
www.mobiletoys.com. This will let you know what wires go to which speakers. i think it's easier to just tap wires with a AA battery and listen to where the static comes from. Hope that helps ya. If you've got more ?s e-mail me
