Sync 3 is the infotainment system for Ford vehicles. I recently updated to Sync 3.4 in my 2019 Mustang GT. Sync 3.4 update has a lot of cool features, however the best is the hidden Sync 3 menu.

Sync 3 hidden menu is a great way to access diagnostics for your Ford vehicle that has Sync 3. Sync 3 hidden menu also lets you change theme for your Sync 3 infotainment system.

Sync 3 hidden menu works for any Ford vehicle running at least Sync 3.0 software version. Sync 3.4 isn't required to access this hidden menu, however I recommend upgrading to Sync 3.4 system for your Ford Vehicle.
