If your vehicle still has sync 2, you need to replace the screen, apim and USB hub with sync 3. None of the updates on this site support sync 2. Plenty of guides out there on how to upgrade on YouTube.
As long as the car wasn’t manufactured in 2020 or later you are good to do the upgrade. Half way through 2018 Ford started to roll out vehicles with SYNC 3.3 instead of 3.0. Only those on 3.3 already were given the update to 3.4 as the partition layout of the system was already supported.
