I picked up on this old thread with the plug in the back of the Becker CDR 220 that you then use the 3.5 m jack to plug into my iPod/iPhone. Easy enough and cheap but when I hit the S (Source) button to switch to AUX the choices I have are FM1, CD, and Magazine. No AUX. I figure okay let's try Magazine which was for the old CD player. What is odd is that Magazine does not hold and it reverts back to FM1 or CD depending what the unit is currently on. Am I doing something wrong? Does anyone have any insight? Thanks in advance.
