part of the problem is that it is an integrate unit ... no need for an AUX when you already have all the devices know to man (back in 1980 )
but at the bottom of the description it says that the two connections (I preseume you do not mean the aerial sockets) are for the headphone and the microphone
someone who has an electrical/electronics background might be able to advise on connecting an iPod headphone output cable to a microphone input cable
not sure how you will go for stereo ...
other clunky alternatives would be those iPod FM transmitters or iPod cassette emulators that people used to use in cars
First B&O (1976) was a Beogram 1500 ... latest (2011) change has been to couple the BL11 with the BL6Ks *sounds superb*
