How did this Navigation update go? I read somewhere that you must do the Sync update first then you can do the Navigation update. I have had no luck getting our 19 Bullitt to update Sync via a USB drive. I have read all directions given at the owners.ford site. I have the USB stick formatted correctly. I have input my VIN number and downloaded the update files and have them all on the USB drive as per their instructions. I go out and plug the drive in to a USB port (I have tried the center console by the shifter one, and the one in the console box). The Sync system flashes a message that it sees the USB stick, but that is it... it never starts to install anything. I read that sometimes you have to wait 8 minutes for it to see the files.... I waited 10 minutes over 3 different attempts, and it just never starts the install. Any suggestions??? This is not rocket science, why does these Sync systems just seems so buggy when it comes to being upgraded? I have seen this in every Sync version in multiple Fords since 2010!!!!
