How can I hook up an ipod to pioneer mosfet 50wx4? i cant get the aux function to show up

if it is a cd player it should have a deh- something number.

Press and hold down the "clock" button. You should see your time start flashing. Normally you set the time with the volume or channel control. Check which control lets the selector jump from "hou" to "minute and set the minutes. To exit setting menu, depress "clock" button again

sometimes the radio has to be off then hold won one of the buttons until it blinks I'm only answering you because you sound flustered good luck....
