One folder and 2 files (Do not unzip the folder.).
Have car running and insert usb that will be recognized by vehicle. You will get a message that this will take about 30mins.
File 3of 14 seems to take the longest, be PATIENT especially file 3.
It will reboot about 2times and do some scheduled maintenance.
At the end you will hear success, but do not remove usb device until you click okay.
