Which Aux cable for Punto factory Blaupunkt?

Hello all

Was wondering if anyone could advise me as to which of these two Aux cables I need to connect an MP3 player to my X reg MK2 Punto Sporting.

My car's fitted with the factory Blaupunkt head unit with cassette player, can't find any model info in the users manual etc, and I'd rather not take the head out more than I need to cos I don't have an unlock code and I want to put off giving a fiat dealer £30 just to click a mouse a few times as long as I can.

Website says both of these are for aftermarket Blaupunkt units so I suppose it might not be either one.

Anyone got any ideas???
