ABSTRACT:
PDA systems, devices and methods are provided for improved navigational route planning. The PDA provides more understandable, accurate and timely information for negotiating a decision point along a route. The PDA includes a processor operable to communicate with a memory. The memory has cartographic data and a route to a desired destination stored therein. The cartographic data includes data indicative of thoroughfares of a plurality of types. A display is provided which is adapted to communicate with the processor and the memory and which is capable of displaying the cartographic data. The PDA processes travel along the route. The PDA recognizes when the device is approaching a decision point in the route and provides to the display an overlay screen on top of any presently displayed screen, the overlay screen adapted to display a preview of a decision point.
