There is an ipod cable available from VW. However, it's very expensive, doesn't charge your unit (unless it's an early ipod/phone) and has only rudimentary control from the head unit. A better option is to forgo the RCD300 & go for the RCD510 sat nav. They can be had from forum members, install easily and add a world of functionality to your Golf. SD card compatability and an on board hard drive (20Gb avaiable space, 10 more used by the nav) make for an easy way to carry a significant chunk of music with you. No leads, no clunky interface, and sat nav as a bonus. If you have a multifunction wheel & highline dash there is the possibility of control from the wheel. Plus, you can add a phone kit at a later date that interfaces with the touchscreen 510 unit. I did, and the 510 is easily the best thing I did to my Golf. Plus if I change, I can remove & refit it in the next one!
