This USB adapter plugs straight into the back of your existing car player. You can attach your iPod, USB player or a SD memory card and play the tracks straight from your stereo. You can use this as a CD changer. You can change tracks and switch folders straight from your player.
I had a Seat Ibiza 99 model and I know how frustrating it is to have a Cassette player or one of those cassette with a wire to attach your MP3 to so I know how useful this is. It is cheap and very very easy to fix yourself.
