Let's start with the truth that Ford doesn't want you to know... you can 100% convert your Sync 2 Equipped Ford Focus ST/SE/Titanium to have Sync 3. All it takes is the right parts, a small jumper harness, and a bit of programming know-how (don't worry, I'll teach you this).
Cars from 2012-2014 & 2015+ have one minor difference when it comes to upgrading from Sync 2 to Sync 3. On the 2012-2014 Ford Focus, you'll need a slightly different hub wiring adapter harness, sold on this site as a
GEN 1 USB Hub Adapter Harness along with a
hub adapter plate in order to fit the new, slightly smaller USB hub into the same spot for an OEM look. On the 2015 cars, you'll just need a
GEN 2 v2 USB Hub Adapter Harness to adapt your current hub to provide power to your new Sync 3 hub.
Before we start, please make sure that you have a Windows laptop handy.
