hey guys,
i've just got an old corolla which i've been driving for about two weeks, but the radio is starting to pack up. i've been looking at replacing it with another toyota branded one (just to be consistent

) and there's a couple on ebay that have come from mr2s which look good (and cheap!).
i got the bloke on ebay to send me a picture of the back of the stereo, and the main socket looks fine (the big white one on the left). Also, the aerial socket looks to be exactly what i need. the only thing that i'm worried about is the other round socket that is marked on my picture.
anyone know what it is & what it's used for? is it essential to the operation of the radio? any help would be much appreciated.
cheers,
joe.
