1. A computer-implemented navigation method for implementation during a navigation routine to direct a user, the navigation method comprising:

  • generating a navigation route;

    receiving a plurality of GPS signals and deriving a plurality of position fixes from the plurality of GPS signals;

    storing the plurality of position fixes;

    comparing the plurality of position fixes with the navigation route;

    determining at least one threshold value based on the comparison of the plurality of position fixes with the navigation route; and

    at least one of generating an updated navigation route to direct the user based on at least one of the plurality of position fixes being distanced from the navigation route a distance greater than the threshold value and not generating an updated navigation route based on the plurality of position fixes not being distanced from the navigation route a distance greater than the threshold value.
