I pulled up the centre control bin today looking for the CD Changer wires. I did see cables wrapped in cloth, but they seemed plugged into something and had that tag around them, like in the pic. I presume those aren't the prewiring cables then?

Is the prewiring just "hanging around" freely? Cuz it may be caught beneath the carpeting.......which would be a PITA should I try to install the changer.

If I get a mp3 capable OEM Changer, would I be able to play mp3s, despite the fact the headunit itself cannot read them?
