A method of operating a portable navigation device (PND) or navigation system is described, together with a computer program for implementing said method and a PND and navigation system capable of carrying out that method. The method includes the steps of providing a means by which a user can identify a specific location or location range on the surface of the earth, which may include the current location of the device or navigation system, and at least temporarily storing said location or range in memory. The method is characterized in that it includes the further steps of presenting to the user a plurality of user-selectable options each indicative of a plurality of transient phenomena, the selection of one or more of which results in the association of that or those phenomena with the identified location or range and the storage of such together therewith as primary information. The method is further characterized in that the primary information is transmitted, either wirelessly or over a physical connection, to a remote device after storage thereof. The transient phenomena may be at least one of phenomena which are likely to have an impact on current or future traffic flow and movement towards, at, and in the vicinity of the particular location or range specified, and phenomena which may be of interest to other device users whose current or future route may pass through or proximate the particular location or range specified. In the former case, the transient phenomena are one or more of traffic congestion characteristics and/or details, accidents and details thereof, thoroughfare diversions, closures and restrictions including road works and repairs, current local weather conditions, and extraordinary vehicle identifications such those being particularly wide, heavy or slow, among others.
