all you need is a $9 tty adapter for the iphone and a $7 cassette adapter to plug into your cassette deck. sounds fantastic !
works for vids or youtube too
along with a car charger you can drive cross country listening to tunes or watching vids on your phone
yeah too bad those tape deck adaptors sound like shit compared to every other way of connecting an ipod to a head unit. tape deck drive motor noise FTL!
