Devices, systems, functional data and methods are provided for biasing an
active location to an acceptable location within a planned route of a map.
The navigational device with map biasing capabilities includes a processor
communicating with a memory. In biasing a map, an active position and a
planned position are received, and an active score and a planned score are
associated with each position, respectively. The active position is
checked to ensure it falls within a second range, and if it does the
active score is made to fall within a first range associated with the
planned score, such that the active position is biased to appear as if it
were the planned position.
