I've just got one of these and fitted it to my leon, bascially connects to the CD changer wiring, I got its so i could use the walkman on my Sony Ericsson W850i through my car speakers, and I'm really iimpressed with it, if anyone has an MP3 player or the likes i definately would reccomend this setup.
Also the benefit of using this and my phone it allows me to use it a handsfree kit! overall very impressed!!!
