if thats the case your stereo does not have changer control

the changer input is socket C3
it doesnt look like that.
ill have to post a picture up.
im not trying to connect a changer.
only trying to replace the broken single cd player with another one.
i removed the original one about 6mths ago but its been binned.
i just dont understand whats gone wrong.
the original one wouldnt play any cd's and now this one cant connect, im sure there is something missing as there was one fitted to it previously
thanks for your help so far, its appreciated
