SYNC3 v3.4.21020

Can anyone confirm if SYNC3 v3.4.21020 is avail for the 2019 SD's. I manually loaded 3.4 build of 20021 last year and would like to know if 21020 will work.

Thanks

Yep it works. I have been using it on several trucks for about a month now.

There is a problem with 21020, lots of stuff doesn't work if you update. It has taken Ford a while to finally fess up, but attached is a TSB that outlines the issues and the resolution. You can either take it to the dealer and they will upgrade (downgrade) the software to a prior version that works, or you can do the same yourself using the CyanLabs Sync3 updater.
