CR-220 Aux not working

[gisound]

I am trying to activate the AUX mode on my radio, by pressing the S button. There is no aux mode. I have enabled the AUX mode by pressing TP and changing AUX to on, but aux does not show up on the source list. Just shows FM2, AM, CD, and Tape. What gives??

I have no idea, but do you have something actually connected to the aux input? Maybe needs a signal on the input to show. Just a suggestion, good luck.
