You can't hook it up to your stock head unit. I bought a Pioneer deck and bought an auxilary input cable that comes out on the passenger side footwell. From there i just run an RCA-headphone cable and it works really well. That was about 3 years ago though and you can just buy head units that have proper ipod charger style plugs and you can navigate your tunes from there, i saw one the other day for about $120, plus your stereo will sound better
