I have an old DEH-P80MP receiver, and in an effort to get aux-in working on it I purchased a CD-RB20 IP-BUS cd changer unit. However after connecting the unit I get no option on the receiver to set to Aux-in. Pressing the SRC button does nothing, and I'm stuck with the tuner...
I'm wondering if I'm doing anything wrong? I've tried going through every setting and there is no settings for enabling cd-changer, aux-in or anything like that
