Bringing back this thread to hopefully get some solutions to my issues. I have a 2014 Fiesta and several months ago I swapped in a Sync 3 from a 2016+. It was not preprogrammed for my car, I just got it from a wrecker. I plugged it into my car and everything worked fine except the navigation, but I assumed that was because I didn't have a GPS antenna plugged in. Fast forward to last weekend and I finally installed a GPS antenna and a back up camera. I bought an OBDLink EX adapter, installed Forscan, saved a copy of my asbuilt (at least I think I did, I'm new to this), and made the various changes to my code. This is where things go south. I tried to change the splash screen, add the backup camera, delete SiriusXM, and add the climate control display. The backup camera worked, but none of the other changes did. Then I tried downloading my asbuilt from the Motorcraft website and uploading that into Forscan. Once I did that, I was able to change the splash screen and add the climate control display, but the camera doesn't work now. Someone on FB said that I should flash my car with a 2016+ asbuilt but I don't know how to get that.
I don't know if it's related but my navigation is also not working after installing the GPS antenna. Before I flashed my asbuilt with the Motorcraft file, my navigation screen showed me parked across the country, most likely wherever the car was when the Sync 3 unit was removed. Even after plugging the antenna in, it was stuck in GA. After flashing my asbuilt with the Motorcraft file, now I get an error that my navigation is not working and when I go to the nav screen it's just blank.
