If you want to add an ipod to an existing oem stereo, there is nothing to do. The ipod has a wireless fm blaster, meaning you can listen to your ipod on a nonexistent radio station (ex. 88.3FM). Yes it is RF which reduces SQ, but your talking about MP3 (a very compressed audio format). If your happy with your current set up, don't change anything your ipod will work fine.
