Introduction

This is a newer safer and more compatible guide to upgrade the stereo in your Ford car.

If you car looks like the left side of this picture you are able to upgrade. otherwise you are out of luck!

Here are some of the benefits of upgrading

  • Android Auto navigation on the small screen in the Dash Cluster / Speedo. (potentially car play aswell)
  • Much snappier and more responsive user interface
  • A nicer looking stock blue theme
  • Newest map data for SatNav
  • If you update your firmware (not the same as this guide) you can also get Radio logos and Calm Mode.
  • There are probably others, if you know of any let me know and i will add them here.

 

I AM NOT RESPONSIBLE FOR YOUR ACTIONS. THIS HAS BEEN EXTENSIVELY TESTED BY MANY PEOPLE WITH MANY DIFFERENT CARS WITH NO ISSUES.
IF YOU PROCEED YOU WILL BE UNABLE TO RETURN TO ANYTHING BELOW 3.2 AFTER FOLLOWING THIS PROCEDURE.

Requirements

  • You will need 1 USB drive between 8-32GB, 8GB is fine for non navigation, 32gb is recommended for navigation.
IF YOU ARE BELOW 3.0 OR UPDATING MAPS ONCE YOU HAVE INSERTED THE USB YOU WILL HAVE FORCED YOUR STEREO IN TO “REFORMAT MODE” IT WILL NO LONGER BOOT NORMALLY UNTIL YOU COMPLETE THIS PROCESS!

Automated Method – Windows Application

 

Syn3 Updater is a is a Windows application created to make the upgrade process of the stereo in your Ford car as simple as possible.

  1. First off...thank you so much for this update. My 2016 F150 feels "new" again. After completing the update, each time I start my truck, the screen informs me that USB is not supported and to remove the device. I don't have anything plugged into the USB's...not even a power cable. Any thoughts on this? Yes, I did the Master Reset after doing the install.

    1. Unfortunately this is due to you having a 2016 car which means you have the old HUB, you will need to replace the USB hub for 2016 cars, you can find more info and part numbers on our forum.
