I'm looking to hook up an iPhone. Sorry if this is answered somewhere else, I didn't quite find what I was looking for with the search....

I have the factory H/K stereo in my 2005 MCS with no CD changer. A few years ago Best Buy installed an XM radio and in the process installed an FM Modulator to tie the XM into the back of the radio.

I later had the XM radio removed, but the wiring and FM Modulator remain. I've got to confess I'm a bit mechanically challenged. I couldn't see the FM modulator when I looked underneath and couldn't tell what I was feeling.

Is there likely to be an AUX port left to use back there or a spot to plug the iphone into the FM modulator? Should I remove the FM modulator if I do find it? Any advice on how best to access this without spending an hour pulling things apart and two days putting it back together?

Pics of the back of the 2005 H/K radio would be a big help. Searched for them on the web and NAM but didn't find them.

Thanks in advance!
