Abstract
The invention relates to a vehicle location display for a navigation system. The vehicle location display operates in either a graphical display mode or a textual display mode. In the graphical display mode the vehicle location display automatically scales the display to display the current location of the vehicle on the street currently being traveled, the previous cross street, the next cross street, and other vehicle information. When traveling on a freeway, the graphical display mode displays the current location of the vehicle on the freeway being traveled, the previous cross street and the next cross street. In the textual display mode the vehicle location display provides the current vehicle location by street or freeway name, city, county, state, latitude and longitude coordinates. In addition, the current compass heading, the previous cross street and the next cross street are provided. Icons displayed in the textual display mode enable a user to rapidly access emergency information and general information.
