1. A system for outputting a relevancy-graded navigation map, comprising:

  • a transceiver to receive map data, vehicle location data, and road data, the map data being indicative of a navigation map configured to be output to an operator of a vehicle inside the vehicle, the map data comprising map elements, each map element indicating a feature of interest to the operator of the vehicle on the navigation map, the location data being indicative of the current location of the vehicle, and the road data being indicative of one or more changeable road conditions;

    means for determining a relevancy parameter for each map element based on the map data related to the map element, the location data, and the road data, and creating a relevancy-graded navigation map using the relevancy parameters;

    a graphical user interface coupled to the vehicle for controlling the output of the relevancy-graded navigation map to the operator of the vehicle and dynamically displaying the relevancy of each map element as the relevancy parameters change in real-time, the dynamic displaying of the relevancy including changing at least one of the an opacity, a saturation, or a color of each map element in response to a real time-time change in relevancy parameter, wherein the relevancy parameter and resulting display of relevancy is determined, at least in part, based on the relevance of each map element to operating the vehicle anda trigger module to generate trigger data after detecting an occurrence of one or more conditions in the vehicle, wherein relevancy parameters are not determined for each map element until the trigger data has been generated,wherein the one or more conditions includes whether the vehicle is moving at or above a certain speed.
