1. A navigation system, comprising:
- a navigation device in communication with a positioning system to determine a current position for the navigation device; and
a set of executable instructions processing on the navigation device that biases the current position of the navigation device to a route position on a planned route when the current position when compared to thorough fare positions is within a threshold, wherein the threshold is a predefined value representing an acceptable delta distance from the route position.

Abstract
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.
