doesnt ur changer play mp3's? do you know how many mp3's you can fit on a cd. i figure itd be almost worth it to leave it alone and take a couple cd's and burn your mp3's on it.
i just dont know that id be hacking into wires that i didnt know what they were. but thats just me.

They're not concealed at all. They're just right under the seat. The pop in and out easily, so I'm not too worried about messing anything up.

Unfortunately, my changer doesn't play MP3s. I wish it did.
