Hi. New to the forums.

I'm finally fed up with no aux input for my ipod on stock '04 head unit with the advanced audio system. Want to replace the unit with something that has an aux in because I think fm modulators are garbage.

My questions are:
1) Can I buy an official saturn ion unit with the aux in from '05-07 off ebay and install that? has anyone here done that if it's possible in the '04 model?
2) if i go the aftermarket route at circuit city what should i look for in a unit? i want to keep the same audio quality..any minimum watts, etc?
