The NaviUpgrade 2012-2014 Ford Focus 4″ to Sync 3 Upgrade harness is perfect for the DIY-er who is looking to add Sync 3 to his or her vehicle. Unlike other sellers, NaviUpgrade was the first to successfully convert a base Ford Focus to have Sync 3.

At NaviUpgrade, we offer two variations of our Ford Focus conversion harness; one for the 2012-2014 Ford Focus and one for the 2012-2014 Ford Focus.

We also offer FREE programming files with your purchase, something no other online store does. This allows you to get up and running quickly using an OBDII dongle, without messing around with a bunch of settings or hex codes in FORScan.

Please feel free to check out our Guides tab for more information on what other hardware you’ll need to complete your upgrade.

We pride ourselves in providing the most value out of any online store when it comes to Sync 3 Upgrades. NaviUpgrade is constantly working on building out resources for our customers and fans to use on their own vehicles. Our goal is to empower all vehicle owners to feel comfortable upgrading their own vehicles. Join us in our Forum and talk about your upgrade experience, or help others with theirs.

    Wiring harness appears to be quality made, plugs fit perfectly and is a great product. Although i was slightly suprised by the lack of instructions/packaging. However the corresponding Youtube video compensated for the lack of instructions, and was very explanatory, easy to follow.

      Hi Jackson — all harnesses are tested before shipping. Please ensure you do not have a faulty APIM module by connecting to FORScan and scanning the car to a new profile. If the APIM is listed but not turning on, you have a faulty module. Please reach out if you have any questions. Thanks!
