Hello.
Cyanlabs does not support changing regions.
Having said that, you should review this thread → Tutorial: Installation of ROW (NNG) Maps on NA 32GB Sync 3 APIM
I’m sure you will find that helpful.
But, if this is true:
You won’t be able to reformat the unit with Syn3updater, so exercise caution.
There’s a workaround for that: FMOD’s universal reformat tool that can be ran against MY20 hardware.
But that’s for you to research.
Again, if your APIM/Screen is MY20, DO NOT REFORMAT IT WITH SYN3UPDATER.
