Sorry, missed your post. The actual part is the USA SPEC PA11-CHR, you can find it on Amazon or other sites. Basically it comes with ports for both an iPod Dock Cable(included) and RCA ports.
I just pulled the bezel off around the HU, unscrewed the four screws and pulled it out a bit. Then you just unplug the CD Changer cable and replace it with the iPod module. I was able to put some double sided tape and mount the module directly above the Head Unit. You can then snake the cables behind the HVAC stuff and toward your center console.
PM me if you need more info or have something specific.
