1. A method for providing navigation guidance for a device travelling within a navigable network represented by an electronic map, the method comprising:
obtaining at a server positional data relating to a movement over time of a plurality of devices traveling in the navigable network;
processing the obtained positional data at the server with reference to the electronic map in order to identify potential inconsistencies in the electronic map in a form of one or more locations within the navigable network where an observed behavior of devices travelling in the navigable network as indicated by the obtained positional data is not consistent with a behavior that would be expected based on the electronic map, the identifying including identifying potential inconsistencies associated with one or more of the devices deviating from the behavior that would be expected based on the electronic map due to one or more local driving preferences;
providing supplemental map information indicative of some or all of the potential inconsistencies identified in the electronic map for output to a navigation device; and
the navigation device then using the provided supplemental map information along with its current version of the electronic map when generating a set of navigation instructions for guiding the device through the navigable network.
