The install isn't really harder then an early model, but you have to get a specific adaptor. Your hookups on the car are more like computer ribbon then a normal wires into connector.
Other then that the most i've had to do for a headunit install is cut away some random plastic behind a stereo (in a firebird) and mount the fit kit and radio.
If you don't have them already you'll want either a crimping kit, or a soldering iron + heatshrink (this is a very nice touch, not much more money either). Then you'll be able to do other wiring as well around the car.
