Experience installing Apple iPod??

Ok, call me crazy, but I want to get an Apple iPod to have every single one of my CD's at my disposal at all times. You can put up to 400 CD's on a singleplayer. Some cars do have the capability to install a cable into the back of the head unit so that you can use the iPod as your "cd" player. Imagine having 4,000 tunes right at your disposal!

Has anyone tried to do this?? I have no idea what that back of my head unit has for inputs. I have a 2002 325XiT. Any thoughts or advice would be appreciated. What inputs are there? Can I wire into the CD changer input (I don't have the cd changer installed).
