So after a couple days on the job Sync 4 won't work on the fiesta, the software is drastically different and the test benches we use are very different from sync 3 benches. Also sync is very platform dependent it's not like a normal desktop program or web page where it can adapt to different display sizes, each display that Ford uses is programmed with a specific version of sync for not only the screen size but also the ac controls, steering wheel controls ect. If I am wrong I'll update this post but from what I know now it doesn't look likely that sync 4 will work with our hardware.
Right now I will actually be working on the final version of Sync 3 before switching to Sync 4 so I may eventually be the guy on here to talk to for Sync 3 issues or questions.
