One cannot install any Gen 7 firmware in a car intended for a different country. For example, attempting to install a 4A01 firmware into a NA01 or an EU01 is not possible. Mazda Connect systems strictly prohibit any change of country or region unless explicitly permitted by the system. In some countries, like Australia and New Zealand, you may be able to install certain Gen 7 EU0* firmware instead of 4A0* firmware, as newly manufactured cars in AU and NZ are now EU compliant but not NA0* compliant. This varies depending on the model year.
