Hello. I live in Korea. I have successfully updated the SYNC system on my 2017 Ford Explorer from 3.0.20204 to 3.4.19200. Even after the update, the SYNC text menu can still be changed to Korean, but the Korean voice and voice commands are not working and only come out in English. I even tried updating to version 20351, just in case, but the Korean voice is still missing. Is it possible to install just the Korean voice package separately? I’ve searched everywhere but can’t find a solution on my own, so I’m asking for help here. * * * **SYNC Region:** ROW **Navigation Variant:** Non Nav **Manufacturer Year:** MY20 **Install Type:** OEM **Old SYNC Version:** 3.0.20204 **New SYNC Version:** 3.4.20136 **Do you have a error message, if so what is it?** no errors **Update Method:** CyanLabs Syn3 Updater **Syn3 Updater Version:** 2.14.2.0 (Stable) **Syn3 Updater Documentation Read:** yes **Syn3 Updater Log File** ```no-highlight I don't have a log file. ``` ---

There is only 1 voice file set for Sync 3 that contains Korean: Region: Non-EU\_NNAV Files: xxxx-14G391-Bx Languages: ARW, DUN, ENA, ENG, ENI, ENU, FRC, FRF, **KOK** , MNC, MNT, PTB, PTP, SPE, SPM, THT Changing the Sync app version and the voice file version should be done together. I would recommend you try the following… | 3.4.21265 | | 3.2.21169 | | --- | --- | --- | | 5U5T-14G381-EU | → | 5U5T-14G391-BP | ---

Thanks for your help with the answer. Are you saying that I need to install the Sync app and voice files from version 3.4.21265, and then install the app and voice files from version 3.2.21169? Is it completely impossible to install only the Korean language files? This article was written using a machine translation tool, so some sentences may be awkward. Thank you for your understanding. ---

No, the Sync 3 app is version 3.4.21265 and the voice file to go with it is 3.2.21169. > [@dreamyfoto](#): > > Is it completely impossible to install only the Korean language files? The Korean voice file is included in this package, not stand alone. ---

Thank you so much for your reply. I don’t know how to install the app version 3.4.21265 and the voice file version 3.2.21169, but I’ll figure it out. Thank you! ---

Thank you! All the issues have been resolved. I used **Syn3updater** to create version **3.4.21265** on a USB stick. I chose the **downgrade** installation option and **EU** for the region. After the installation was complete, I deleted the voice files. After that, I manually downloaded the voice package for version **3.2.21169** and copied it to the **‘SyncMyRide’** folder on the USB. I then edited the voice file names in the **‘reformat.lst’** and **‘autoinstll.lst’** files to match the downloaded voice file name. When I plugged the USB stick I made into my Explorer, it successfully downgraded, and the installation of version **3.4.21265** was completed. And of course, the Korean voice and commands are working perfectly! This text was written using Google Translate. Please understand that there may be some awkward sentences. ---
