I have a new Holden wagon with the AUX input for an external MP3 player and an Ipod Nano I wish to use in the car. I have scoured the Apple store and Holden website and can't find any reference to a connecting cord. Can anyone enlighten me what I need to buy and where I can purchase it? I currently use a Belkin FM transmitter thingo which gives crappy sound as it relies on reception through a spare radio station.
