iPod Interfaces

Has anyone successfully integrated an iPod into their 2003 or newer range Rover? If so, what did you use and what functionality are you enjoying? I previously installed a toggle switch and was able to plug my iPod in using the headphone port and played iPod thru the CD changer mode. Switching the toggle back and forth meant I could jump back and forth between iPod and CD changer. Any help is appreciated. Thanks all, Roy
