In the factory, the vehicle is produced specifically for a certain country and complies with this country's registration regulations valid at the time of vehicle production.
If the vehicle is going to be sold in another country or is going to be used in another country for an extended period, the legal requirements applicable in that country must be observed.
In some cases, certain equipment will have to be fitted or removed and functions deactivated. The service scope and service types could also be affected. This is particularly important if the vehicle is driven in another climate region for a long period of time.
Because different frequency bands are used in different countries, the factory-fitted radio or navigation system may not work in other countries.
