Patent Images
1. A navigation device programmed with a map database and software that enables a route to be planned between two user-defined places, wherein the device is further programmed to be able to display a navigation map on a touch screen display, the navigation map showing a current position of the device on a planned route;
- and wherein the device is further programmed to task away completely from the navigation map, when the touch screen display showing the navigation map screen is touched by a user, to a menu screen which displays a plurality of touch-selectable options relating to route calculation, the touch activation of at least one of which initiates a re-calculation of the route to find a detour away from the planned route.

15. A method of displaying navigation information, the method being deployed in a navigation device programmed with a map database and software that enables a route to be planned between two user-defined places, wherein the device is further programmed to be able to display a navigation map on a touch screen display, the map showing the current position of the device on a planned route, the method comprising:
-
tasking away completely from the navigation map to a menu screen which displays a plurality of user selectable options relating to route calculation by touching the touch screen display showing the navigation map; and initiating a re-calculation of the route to find a detour away from the planned route by touching at least one of the plurality of user selectable options displayed on the display screen.
