Region Change for Imported car

[Nate118I]

hey all,

recently I imported a series 1 118I 2019 BMW car from Japan to Cyprus.

I would like to understand what is the best and simple way to change the region in the NAV maps? do I even need to change the region? or can I upload EU map and the software will run them simultaneously?

VIN - WBA1R520005C82521


Thanks to the helpers!
