No, it’s the system voice file for Sync commands only, not NAV.

That worked, thanks!
Done the upgrade from 3.0 20205 and all works well, MINUS ambient light.
Ambient light controls does nothing!
No lights, althow I’ve tried all the colors, all the settings.
give it time they will start working.
one more note that could be added on 21194 is that it fixes the android auto incoming call bug that mutes the other person for some reason.

Upgraded Sync 3.4.20136 to 21194 but keeping the existing maps. It fixes previous issues about home screen showing the radio is on displaying the last tuned frequency while actually it is off. Now the update fixes everything with enhancements like a background image of the artist when you play songs. One thing I noticed though is that the screen lag is very noticeable.

Thanks for this. Does this release fix the issue with the older screens where you get the flickering issue as it tries to fade between the light sensor reading, and the auto dim option that was disabled after early 3.4 versions?
Thanks

It is reported that it does. I personally have not tested this. This issue is vehicle model dependent, so your experience may be different.
The illumination dimming is controlled through the vehicle dimming controls, no longer thru the Sync controls, except at night. This change was made in the early versions of 3.4 by design.
Thanks. In my car, I have a separate dash button that controls the in car illumination level, but the Sync 3.4 screen still had a mind of its own and tried to auto dim when the ambient light level changes. But it goes mad, causes a flicker effect in the screen (even on dark mode).
The earlier versions of 3.4 and all versions of 3.0 had the option to disable auto dim in the sync settings, so hopefully this update resolves the above!
Hi, upgraded my focus from 3.4.19101 to 3.4.21194, the air conditioning control disappeared and i think that the system now have more delay.
Greetings,
Perform a master reset. About the AC commands it’s not a bug, it was a bug for you to have them in the past build, and now that bug is fixed.
You can enable that via forscan if you like, but why would you, since you have a dedicated physical panel to control the AC.

I just completed the update of the sync 3.0.17276 directly to 3/4/21194 as well updating the navigation from NA 1.16 to NA 2.20 in my 2018 F150. Thanks Cyanlabs this has been excellent. I had hesitated to complete the update in the past as it would need to ensure to select the correct package, format, etc but the latest tool 2.10.3.0 is great tool and making the update is a breeze. The whole process takes about a few hrs from downloading the file and installing on my vehicle. It took a bit longer to download all the files cause for some reason I keep getting message download failed and took several tries. Installing on the vehicle takes about 30 mins (with the maps update). I am glad it was able to keep all the setting that I had modified with fordscan. I had added subwoofer and also modify the equalizer setting and thought I may have to make the changes again with fordscan but turn out all setting was intact after the update. I notice however with this latest sync 3.4 boot up is slightly slower than 3.0 and voice prompt is a little bit choppy. I am thinking may be newer Sync now require faster processor/more memory and hence I am seeing these effect?. Overall I am glad I was able to update it successfully. Thanks again Cyanlabs Team.

just completed install/upgrade from stock 2017 escape titanium with maps. sync 3 v3.0 build 20204. now running sync 3.4.21194 with 2.20(2020) - na maps. had to do a reset several times before it the new maps showed up properly. drove it today and works without issue so far. the cable i was using for android auto wasnt working after the upgrade so changed cable to the oem cable with the one plus nord 10 i am using and android auto works now.
btw this update took about 45 minutes to complete.
Continuing the discussion from Sync 3.4.21194 - Feedback & Issues:
My language version is marked as UK English instead of USA English, some of the ford apps won’t work. Not the end of the world but is there a fix for this…
I am on 3.4.21194 with latest maps.
Other than that works perfectly
Make sure you have the proper voice file installed for NA, and if you have modified your region to 5753 for NAV in motion it will do this. With 3.4.21194, I suggest returning your setting to 5553 for US as some of the annoyances in the NAV have been modified.
