I downloaded the update for my new 2013 eco boost to my computer and put it on a thumb drive. The directions are not as clear as I though they were and there are not many images helping the install. Where exactly do I install the thumb drive into the truck. I tried it in the center compartment in the 2 usb ports but it says no readable data. I also stated under the dash, in the computer, ect. but I have yet to find the port in reference. Also do I need to have a thumb drive that is new (clean) without other data? This has gotten pretty irritating in trying to update the sync which has also been irritating the last week or so with not functioning properly. Any help on this would be great. In the email i received and online it shows the 10 steps but doesn't show how to install. Thanks in advance guys!
