Navigation system, method and device with automatic next turn page
First Claim
1. An electronic navigational aid device with an automatic next turn page, comprising:
- a processor;
a memory adapted to communicate to the processor, the memory having cartographic data and a route to a desired destination stored therein, the cartographic data including data indicative of thoroughfares of a plurality of types;
a display adapted to communicate with the processor and the memory and capable of displaying the cartographic data;
wherein the device processes travel along the route;
wherein the device 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 the decision point, including a highlighted portion indicating a course to follow through the decision point, and the overlay screen displays motion of the device on the course through the decision point; and
wherein insignificant detail is removed from the overlay screen at the decision point based on a set of criteria.

Abstract
Systems, devices and methods are provided for an improved navigational route planning device which provides more understandable, accurate and timely information for negotiating a decision point along a route. The navigational aid device includes a processor adapted 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 device processes travel along the route. The device 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.
