1. A method of operating a navigation system in a vehicle comprising: invoking an off-road mode of the navigation system; displaying a first off-road terrain on a display of the navigation system in a first instance; displaying a first present location of the vehicle on the display; inputting a first user-input off-road destination into the navigation system; inputting at least one first user-input off-road waypoint into the navigation system; displaying straight line trajectories between a start point and the first of said at least one first user-input off-road waypoint, between any consecutive waypoints of said at least one first user-input off-road waypoint and between the last of said at least one first user-input off-road waypoint and the destination on a display of the navigation system; displaying a first real-time path of on-screen breadcrumbs as the vehicle travels off-road; determining if the vehicle is within a first distance from one of said at least one first user-input off-road waypoint; determining if an engine of the vehicle is turned off; determining if the vehicle is within a second distance, smaller than the first distance, from the one of said at least one first user-input off-road waypoint if it is determined that the vehicle is within the first distance from the one of said at least one first user-input off-road waypoint and the engine is not turned off; and relocating, on the display, a position of said one of said at least one user-entered off-road waypoint from a currently displayed position to a position on the display of a closest on-screen breadcrumb of the first real-time path when the vehicle is within the first distance from said at least one first user-input off-road waypoint and the engine is turned off or when the vehicle is within the second distance from said at least one first user-input off-road waypoint.
