Just thought I'd warn people that this cable
http://cgi.ebay.com.au/Hyundai-ipod-interfaceis not the same as the picture, you don't get the extra rings on the 3.5mm plug so you can't control the iPod from the deck. I bought one after asking the seller if it was the same as the picture but it turned out to be a generic plug.
I've got the original cable but thought the split usb/3.5mm plugs would make using a usb hub possible and allow for switching betwen usb stick and iPod easily. Anyway cable was no good, I did get my money back though so all is well.
