I am posting to see if anyone has come across a relatively easy way to hardwire a mp3 player (ipod) into the factory stereo. I have a 2005 forester with the factory 6 disc changer and have been told that FM modulator is the only way to go unless I want to get an aftermarket stereo. I was also informed that if I went this route that I would then loose my sub. Anyone else dealing with this?

I would suspect that the easiest way to do what you want to do is to tap into the audio lines between the CD changer and the head unit. If I was doing this I would install a switch to tie either system to the head unit and not just run them in parallel, though this may not effect the two units audio if you do. You should be able to keep the sub working by doing it this way. I don't have any wiring info for doing this mod.
