auxiliary input for the factory 6 CD changer

[Space_Cowboy]

There was another thread that discussed putting in some sort of jack in that dash dummy button next to the instrument cluster that would be kind of an aux. input to the stereo. I guess my question is, has anybody done this? Also, I know that the single CD player doesn't have aux. inputs, but does the 6-cd player have them? It would be great to wire something through there so you could maybe play mp3's or....gasp...tapes...
