Main reason to get 3.4 update on Sync3 was to have turn-by-turn direction on instrument cluster.

Sync 3 Update
(Upgrading Sync3 software version from 3.0 to 3.4)
A much delayed update from my side . Delayed? Well, I had done a FORScan coding which requires Sync3 software version to be 3.4.
Ford never released 3.4 version for a BS-IV EcoSport, so updating the software through official way as mentioned in this thread/post. Also, this is not going to be as crazy as this thread.
Disclaimer: I am in no way related to CyanLabs in any which ways. This process can be risky, and in worse situation can brick Sync 3 system. Also, this cannot be done on a FlyAudio. Only applicable for a Sync3 system.
Sharing following steps to update Sync3 Software Version through an unofficial way:
You need to now the current Software Version of your car's Sync3 System. This can be found by toggling to Settings => General => About Sync. The following screen should show up, take a picture of the same as we will require the software version (red box). In my case it was 3.0 Build 20204.
Through this link, download Syn3 Updater on a Windows Laptop.
After downloading Syn3 Updater, open the application.
- The software version as noted down in Step 1 needs to be filed in 'full version' box (In my case it has to be typed as '3.0.20204').
- Region to be selected from dropdown 'Middle East, Africa, India...'.
- Navigation should be toggled-off, as in India EcoSport does not get Build-in Navigation.
- The configuration can be as default (have changed it in the below attached screenshot).
- Application Option can be ignored.
- Advanced Options, toggle on the 'Edit Advanced Options?'. If your car is manufactured in 2020 or after 2020, enable the 'MY20 Protection'. If the car is a BS-IV or build before 2020, disable the 'MY20 Protection'.
- For Install Mode, choose 'reformat' from the drop down menu.
- Insert a pen drive which has no data, as the same will be formatted. For non-navigation software, 8GB USB pen drive is sufficient, for choosing the exact requirement on pen drive refer the next picture.
Now we can apply the settings.
The next screen on Syn3 Updater will require to choose the USB Pendrive. For New Verion, choose the same region as before, select the latest version (in my case it was 3.4.23188). Leave the map version, if your car does not have a build-in navigation. The last step is to click on 'Start'. A stable WiFi is required, also the download duration will depend upon the WiFi speed.
Upon successful download, it will format and rename the pendrive. Once done, eject the pendrive and hop in to your car.
Major work being done, unlock the car, slip into the driver's seat, close the drivers door and wait for the Sync3 display to turn off (do not start the car or put the car in accessory mode). Insert the pen drive in either of the USB port, switch on the car (keep the engine running during the software update process). This step will take time, sharing a few pictures (ignore my ugly editing). Do not remove the pen drive, unless the same is shown on the Sync3 display.
Once the process gets completed, it'll request you to remove the pen drive. Now the pen drive can be ejected (simply pull out the pen drive). The Sync3 will reboot, and after this hard work, you'll be rewarded with the similar below screen . After the reboot, it is recommended to format the Sync3 system for minor software glitches. Also, I noticed the bluetooth name has been renamed to 'Ford EcoSport' (earlier it used to be 'Bluetooth') hence, will require re-pairing of devices.
Main reason to get 3.4 update on Sync3 was to have turn-by-turn direction on IC, sadly it does not work through Apple Carplay even on iOS 17.4.1 (should work through Android Auto).
