Hello.
What you need to do is changing regions, but we do not support it. You can take a look at the guide “Current EU Maps Installation on US Imported Vehicles”, but you are on your own (since we do not support it).
Also, since your unit is MY20 you can’t reformat it with syn3updater because you will brick it, but you can look into jailbreaking the unit and then reformatting it with FMODS’ universal reformat package that can handle MY20 hardware. We do not support jailbreak either.
