mp3 Adapters for s2000

[gizorge8]

Hey, I'm a new member here, so i'm sorry if this info is already posted under another thread. However i've had my s' for about 3 months now, and am really in love with the car. (this coming from someone who just got out of a 400hp 2003 ford mustang mach 1 & a 400+hp 1999 Ford lightning).

However I'm wanting to probably keep my stock head unit and just replace the stock speakers as far as audio goes. And i guess my question is this: What do i need to hook up an mp3 player through the back of my STOCK head unit? I've searched around, but am not for sure exactly what i need.

I'm assuming it'll plug in through the cd changer jack in the back of the head unit, or the auxilory jack, either or.

Any help (hardware names, places to purchase, websites, etc.) would be greatly appreciated.
