I tried to update my Sync 3 to version 3.4 on my 2019 Ford Ecosport.
But I believe that this version was incompatible, the update went well but the screen was cropped (I believe it’s because my screen is smaller).
I tried some new updates but the message “Updating system” stays on the screen but nothing happens. My Sync has no navigation.
I’m very layman on this topic.
Is it possible to work around this problem?
Sync 3.4 for the 4" screen would be 5U5T-14G381-FS 409Mb Sync3 v3.4.21098 08.04.2021
The log indicates this is loaded on the unit:
5U5T-14G381-ET (This is the 8" Screen version of the Sync app.)
5U5T-14G391-DP (Voice)
4U5T-14G423-DC Gracenotes)
The reason nothing happens for updating the unit is because there is only 235MB of memory left. You will need to delete Gracenotes from the unit to be able to load the correct Sync file for the 4" screen. This can be done with the Syn3 Updater, make a Gracenotes deletion usb and run that.
