But how are those options as far as quality loss goes? I think I recall the cassette converter deal is equal to cassette audio quality, which is far worse than CD quality.
Any idea if the MP3 inputs in the newer cars are equal to CD quality?
My car has an AUX input by the radio and CD player, and with a Radio Shack cord to an MP3 player it sounds really good.
As for cassettes, when I had cassette players in my previous cars, they sounded crummy with a commercial cassette, but when I made a cassette from a CD onto a decent grade TDK tape through my home stereo and equalizer, those sounded darn good. Once I bought that home system and started making my own tapes, I never bought another commercial cassette again, just CDs. The dual deck is still in the rack, but since I got my newest car 4+ years ago, I don't use it at all.
