    in the 2007 Saturn Ion model, with the factory stereo what cord do you use to hook up an ipod? a regular aux cord doesn’t fit

    Andrea, we suggest you install a car auxiliary input adapter. This aux input adapter will allow you to input any portable music player, mp3 player, Apple iPod or Apple iPhone into your factory stereo. This is the easiest and most cost effective way to add an audio input into your factory radio directly rather than over the air. Here is the adapter you will need:

    If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2007 Saturn Ion aux input adapter install.
