     The red circled part on the image at the above needs to connect to the HMI USB Box color green. It is usually located around the Glove box or just around the dash part back of the radio. Please check this video to see the location of the HMI in some instances, its at the back of radio only and not on the glove box.
     
     If on the Glovebox for HMI -
     

If on the back of Radio -

The HMI will look like this and the Green encircled needs to be unplugged and need to connect our USB Audio box adaptor on the encircled one. The one that you removed from the green, needs to connect to the Factory USB adaptor (blue part). Then the USB side connects to USB 1 or 2 from us.
