Cheers guys!
Yeah its an aux cable, that was one of the main reasons why i wanted an Up, for the ipod connection! It was only a fiver.
I didn't know you could get this combination either, it was a ready-built one that the dealer had pre-ordered and it was just waiting at the factory. As my only criteria was "I want a white one" they gave me this, and I'm really pleased its that colour inside with the dull dash rather than the shiny one, because it won't reflect!
