BMan - the MDI cable that comes standard with the car is an MDI USB Cable. No, you cannot hook up your own white iPod/iphone cable to the MDI USB cable that comes with the car. It is not compatible. You need to purchase the specific iPod MDI cable. Like what most of the forum users have suggested, do a search via eBay and purchase an iPod MDI cable. They're approx $30+ AUD and much cheaper than the Dealer ipod/iphone MDI cable option! I purchased an MDI ipod/iphone cable from eBay and I'm currently using it in my new TDI. Works like a charm. :)
