Being that iPods, iPads, and iPhones are linked and policed through iTunes, the simple quick answer is no. You are going to have to eliminate the copyrights and load them onto a thumb drive and load them that way. You can, however get a cable and plug that into the head unit and the iPod and play them that way.
Your owner's manual should provide the information on the cable, as well as how large the hard drive is on the head unit. If you don't have one, google your car and search for an owner's manual through a pdf file or online somewhere.
By the way, I haven't heard anywhere that you can actually load music or any media directly to the head unit. You need to plug a thumb drive or an iPod type media player into one of the USB ports on the lower dash.
