You are forcing installation modes. Do not do this. The 2 previous logs posted showed forced installations and the options were not configured correctly.
The settings should be:
PREVIOUS CONFIGURATION
Version: 3.4.20282
Region: ROW
Navigation: True
Install Mode: autodetect
Install Mode Overridden: False
My20 Protection Enabled: False
Since you are on 3.4.20282, you need to downgrade the APIM first to Sync 3.3.19052. The Syn3 Updater app will select this for you from the settings above. Once the unit downgrades to 3.3.19052, then the installation will use the reformat tool to wipe the previous versions and install the new Sync version and maps.
However, the navigation will not work correctly if the region information is not changed. This needs to be done in the APIM and ACM. See this tutorial for guidance.
