AW: Mainly for cost reasons. While TomTom and also HERE supply map data to navigation software manufacturers against a fee, such data is quite expensive for larger regions like Europe, as it requires constant updating.

The NNG map data used in this navigation software package is based on the raw data from Open Street Map, which is a refined version of the base map data with additional data layers added by NNG Maps.

The OSM data with a license for free use enables companies like NNG to provide cost-efficient navigation software products for normal passenger car use.
