Dynamically downloading map data to a wireless communications device is achieved by determining a map data density for an area of interest and then dynamically downloading and optionally also dynamically displaying the map data for the area of interest based on the map data density. For areas of interest with low map data density, this technology has the effect of downloading more map data so that the map is displayed with more detail than would conventionally be obtained. Conversely, for areas of interest with excessively high map data density, dynamic downloading and display can reduce the onscreen map density for a less crowded map.
