Abstract:
A method and device are disclosed for navigation. In at least one embodiment, the method includes determining, in a navigation device, at least one of, when an instruction for travel along a route of travel is not due to be output for a distance exceeding a distance threshold, and when no instruction for travel along the travel route is output for a period of time exceeding a time threshold; and placing the navigation device in a power conserving mode upon the determination being made. In at least one embodiment, the navigation device includes a processor to determine at least one of, when an instruction for travel along a route of travel is not due to be output for a distance exceeding a distance threshold, and when no instruction for travel along the travel route is output for a period of time exceeding a time threshold, the processor placing the navigation device in a power conserving mode upon the determination being made.
