1) enter the last 7 of your VIN here:

2) download the file to a USB stick
3) plug the USB stick into the USB port in the front console
4) go to the software update menu on your drive and select update software.
That is it you are done. I just updated my 2014 the other day, I thought it was odd that that a new car came with outdated software from the factory, updated 1 version.
