Some SYNC 3 updates appear to only be available over the air (i.e. through Wi-Fi) and don't show up as an available update on the Lincoln or Ford Owner sites. Your SYNC may report as up-to-date, even though you have a constant "Download" attempt on your SYNC 3 unit every time you get in the vehicle.
My goal is to provide these harder to find files here as complete install-ready packages, so you can complete these updates using a USB drive instead of the unreliable Wi-Fi update process and finally get rid of the "Downloading System Update" message. If you have any suggestions (including the file names that your SYNC may be trying to download, but aren't available here), please email email@example.com
Find the file your SYNC 3 system is attempting to download below, and click it to begin the download. The file will be a ZIP file, just like the one you receive from the Lincoln and Ford Owner websites. Simply download it, extract it, and move the one file (autoinstall.lst) and the one folder to the root (main) folder on a USB drive formatted as exFAT (Master Boot Record).
