I bought the proper cable from Mitsubishi at the radio end it is a large grey connector at the other a normal usb the radio socket is situated to the extreme left as you look at the radio front and is coloured grey .It can be seen if you look under the dash at the radio better to remove the glove compartment lid just clips in you then can put the cable into the radio without removing it best to have a torch handy so you can see where the cable goes hope this helps.
