I have an iPod iPhone 4 retrofit cable.it plugs onto the back of bmw e46 business radio and allows you to use iPod instead of cd changer.also has a USB port if you wish to charge your iPod.the plug is an apple plug not a cheap copy takes 15 mins to install all you do is remove cd changer cable from the back of your radio and instal this plug in its place
