connecting ipod with the glovebox cable

Hi guys,

I want to connect the ipod to the usb/aux ? cable which is the glovebox however when I insert the cable into the ipod nothing happens. I have changed the audio mode via the buttons on the steering column to aux but no luck.

Any advice ?

Cheers
 
I didn't get as far as the wires, just tried the different inputs and resorted to my trusty FM transmitter! [emoji6]
