Hello,
I just bought something similar for my dad's Beocenter 9000.
I opted for the Terratec Noxon iRadio for iPod.
http://www.terratec.net/en/products/NOXON_iRadio_for_iPod_16231.html
manual can be found here: http://ftp.terratec.de/HomeEntertainment/NOXON_iRadio_for_iPod/Manual/NOXON_iRadio_for_iPod_Manual_GB.PDF
Advantage: Also an Ipod dock included (= only one cable to connect "two things" an internet radio and the ipod), plus can stream music, has a timer set to go on simultanously as the B&O, can be used seperately, nice build quality and screen, remote control. can be used seperately as a stand alone radio
Little strange: the "line-out" can be controlled by the volume button
203euro (at redcoon, sold out on Amazon)
He's quite happy.
