Some buddies of mine that own an install shop did it for me. I didn't want to take the chance of messing something up, haha.
Yeah, it's set up so I can watch videos on the road. I have a 120 GB iPod dedicated to it in my glovebox with about 25 movies, 26 GB of music and about 40 music videos. I'm on a road trip from Minnesota to Indy right now, just finished watching Ginger Snaps.
