My 1998 Camry with stock stereo system has a tape and CD player — but no aux input. Right now I'm using a tape adapter with my iPod Shuffle, but it sounds like crap compared to the radio or CDs. I'm wondering what my options would be if I wanted to add aux input. Would i have to replace a bunch of components? Could I do it myself? How expensive would it be? I don't want or need anything that integrates with iPods (such a feature would be useless with my Shuffle anyway). Also, if there's a really active/helpful car/Camry forum that any of you know of that I could go ask this at, that'd be cool too.
