Get ahold of the install guides from this site, become very familiar with them and go to work. If you have the single din kit and the harness that'll plug into your factory one, you're set to dive in. If you're doing just the head unit it should be a 10-15 minute job.
Once you get into it if you get stuck or have problems then hit people up w/specific questions, you'll be better off that way, trust me.
