stereo wiring diagram?

Bought my ML used and it only has a tape deck (the CD-changer was broken). I am wanting to swap out the deck for one that plays MP3's. Any idea where I can get a wiring diagram or instructions?

Thanks!

Crutch field has the wire harness install kit and the tool for removing the factory radio. Any after market din sized stereo will work. Pioneer is has an excellent selection of head units that will play mp3's.

Good luck, stereos on ML's are a bugger to replace...

I have a kenwood head unit. I changed it out myself I got the wiring harness at audio express I did it in about one hour

I just replaced my BOSE tape deck with an aftermarket JVC. What you need is this wiring harness http://cgi.ebay.com/ebaymotors/MERCEDES-STEREO-WIRING-RADIO-WIRE-HARNESS-AMP-INTEGRATI_W0QQcmdZViewItemQQcategoryZ38636QQitemZ7 989838379QQrdZ1QQsspagenameZWDVW
