<p>A navigation device, method and computer program storage device cooperate to seamlessly provide electronic navigational assistance, despite the user electing to use different modes to transportation, such as motored vehicle, by foot, or by bicycle, for example during a single trip. In addition to prospective (forward looking) navigation assistance, retrospective assistance is offered as well by the device collecting and storing actual traversal path of the device even when multiple modes of transportation are used in a single trip.
