Hey French, if you go back to my post reply from 3-27-14 , I have a link to the update site. Enter vin request and go on from there. If you are not sure of my-gig model, I think it will know from vin as long as it is original equipment.
That picture has nothing to do with model number. It is usually located on front bottom right of unit, below the audio jack. Go here if need be to help identify yours. (Uconnect | Support | System Identification )
