This Sync 3.4 update (build 22251) worked well, and thanks to CyanLabs for posting the file to download. I appreciate it. It is nice not to have the severe-delay response of the Sync 3 to a screen request. The “Biden-brain” lag is gone!! I installed this update in late December 2022.

Hi all,
I just used the updater to get from SYNC 3 to 3.4 and also new maps. The process worked flawlessly. My 2018 Mustang GT would not update at all using the Ford web page and instructions. I followed the FORD instructions to the letter, and no dice. The Cyan USB update was smooth and after downloading the files onto a USB it took just over 27 minutes to get the update installed.


Glad it worked out for you :slight_smile:

I tried the official ford update via usb and got the "updating system software " message on the top.

I reset the APIM and did a master reset.
Message gone.
I used this update and the update went through.
One annoying bug with 1.0 was that it didn’t remember my home network password.
I just did this 2 days ago, haven’t explored everything yet…kudos to the people(s) behind this…the latest NA 2 21 maps is nice.

Updated my Fiesta 2018 titanium yesterday.
50 min of stress but everything is good !
thank you so much for your works !

I’m prob not asking this in the right place but I have a 2019 Escape.
Current software is 3.0.20204
What is the highest version to update from here and what advantages will I get if I do update it?
If there is a page I’m missing that shows this information apologize in advance but this site is difficult to navigate for a first time user.

You are correct, it’s not the place.

3.4.23088, basically new UI and maps.

If you have further questions please do not post them here since it’s offtopic: create a new thread instead.

Ford Focus 2017 from USA but car was imported to Poland.
I had sync 3.3 19052 + maps F8
I wanted the new update sync for Europe + maps and during update I got error:

What goes wrong? How can I fix it?
