Xc90 stereo/iPhone/iPod integration

[music2ears]

Hi guys. I am a proud owner of a 2005 xc90 executive. Does anyone have any ideas or knowledge regarding the fitting of an iPod/iPhone dock? I'm not to concerned with the phone side of things as the xc has built-in communication pack. I just wish on longer journeys I could plug in my nice new iPhone 4s and listen so some of my tunes. ;) the car stereo has cd & minidisc (which I own none of) but I can't see anyway to connect my music.
Many thanks in advance guys. ;)
Steve.
