A guide on updating your Ford Sync 3 based car to the latest Sync 3.4 version using Syn3 Updater to make the process as simple as possible for you!

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 
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.

Can 3.3 build 18201 be updated to 3.4
Yes
Thanks! Just finished it and working great.
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.
Thanks!
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.
