1. A method comprising:
identifying, via a processor using map data, a plurality of geographic areas in which a vehicle is to travel along a selected route to a destination;
identifying, via the processor using the map data, a plurality of map tiles corresponding to the plurality of geographic areas, such that each of the plurality of map tiles corresponds to a different one of the plurality of geographic areas;
obtaining data access information for each of the plurality of geographic areas, including cellular reception information for each of the plurality of geographic areas;
determining, via the processor, groups of consecutive map tiles with corresponding geographic areas with reduced or no cellular reception; and
determining, via the processor, a prioritized sequence for downloading the plurality of map tiles, based on the data access information for the plurality of geographic areas, including based on the cellular reception information for the plurality of geographic areas, and including based on the groups of consecutive map tiles with corresponding geographic areas with reduced or no cellular reception.
