Overview

The NaviUpgrade 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 2015-2018 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.

    I got this harness to upgrade my 2017 ST1 to sync 3 and it arrived very fast. It's very simple without extra connections I've seen on others and is working phenomenally. The help I got from Brian with the install was a huge part. I will definitely be looking for more products and can't recommend this enough. Such a huge upgrade.

    Harness came and worked as described. Shipping was fast, customer service was excellent. Couldn’t recommend NaviUpgrade any more for their services, if you’re looking to swapping your base sync unit to sync 3 highly recommend them.

    I couldn’t recommend this harness more. Not only does it come with all the needed programming, but it’s super easy to do, especially if you follow along with Brian’s videos on the NaviUpgrade YouTube channel. I had a question during my installation and Brian had the answers to me within minutes. If you’re going to do the swap, do it right and get this harness.

    Loving my Sync 3 system and this wiring harness made it easy. The documentation was great and I was able to complete the update in about 3 hours on a Saturday afternoon.

    This harness and the included asbuilt files make the Sync 1 -> Sync 3 upgrade a breeze. This is an afternoon of work (at most), that totally changes your interior. Navi-Upgrade shipped very quickly, and between the youtube videos, and guide on the website it's easy to source all of the required parts. I highly recommend this upgrade to anyone with Sync 1!
