Hi & congratulations on your pruchases
To add soft buttons to the Beo4 you need to use this routine:
1/ press and hold the STANDBY button [●] and then press [LIST] together with the STANDBY, now let go
2/ "ADD?" will appear in the little display window
3/ press [GO] to get the soft buttons you can add
4/ press [LIST] repeatedly to scroll through the list of buttons to add (or use [v] or
)
5/ eventually you will see "A.AUX"
6/ press [GO] to select "A.AUX"
7/ "ADDED" will appear in the little display window
now any time you need the AUX just keep pressing [LIST] until you see "A.AUX" and then press [GO] and you should have your iPod connected and then you can press play on the iPod or whatever :-)
Good luck !
First B&O (1976) was a Beogram 1500 ... latest (2011) change has been to couple the BL11 with the BL6Ks *sounds superb*
