I bought a pre-owned 2018 Mazda Demio DJ from Japan which is in immaculate condition. However, the Navigator is set on Japan and I have been told that it is not possible to use a Europe sd card for it as it will not work. In fact, I tries a Europe sd card and the system tells me that the Navigator is not installed even though I know that it is installed and worked with a Japan sd card. Any help on this from anyone, please??
