Syn3 Updater 2.0 is a completely new design, both for the UI and the backend.

Syn3 Updater 2.0 will allow you to download your desired version of Sync 3 from the official Ford links and once the download has completed it will automatically prepare the USB Drive ready for you to insert into your car. This application prevents user error from wrongly formatted or partitioned USB drives and will ensure the correct update method is used.

New 2.0 Features

  • Better handling of the downloading and copying resulting in less instability.
  • A brand new UI written in WPF rather than the outdated WinForms, this should scale better on scaled computers.
  • Utility tab – Here you can generate and read the official ford log file, remove gracenotes, shrink your voice package and much more
  • Parsing of the ford interrogator log files to allow you to view your as built information without needing to dump it from ForScan or ETIS.
  • Open source, available on GitHub.


  • Always up to date download link for the reformat tool.
  • Auto detection of the best install mode (autoinstall, reformat or downgrade) with only 1 USB drive.
  • Option to unselect individual packages if desired.
  • Option to install “With Nav” or “Without Nav”.
  • Multiple validation processes (filesize and CRC checks) to ensure downloads and copies are successful.
  • Detailed information for each release showing the “APPS” version and the “MAPS” version specific to your region.
  • Allow upgrading to newer versions of Sync than officially supported by your car (all SYNC 3 versions).
  • Automatic update check to ensure you are on the latest version.
  • Multilanguage capable (translations are crowd sourced)
  • Uploading log function to allow easy troubleshooting

Here are some of the benefits of upgrading to Sync 3.4+

  • Potentially Android Auto navigation on the small screen (IPC).
  • Much snappier and more responsive user interface.
  • A nicer looking stock blue theme.
  • Newest map data for navigation.
  • If you update your APIM firmware you can also get Radio logos and Calm Mode.
  • Much better looking media interface for 3.4.20196 and above.
