1. A method for displaying map information on a portable computing device, comprising:
- when the portable computing device is approaching a location at which maneuvering guidance is to be provided for following a route, presenting a sequence of alternating images on a display screen of the portable computing device,wherein one of the alternating images is presented on the display screen at a time,wherein the alternating images include a first image and a second image,wherein the first image is either an overhead view map image or one of a perspective view map image and a stylized image of an upcoming maneuver,wherein if the first image is the overhead view map image, the second image is one of the perspective view map image and the stylized image of the upcoming maneuver, andwherein if the first image is one of the perspective view map image and the stylized image of the upcoming maneuver, the second image is the overhead view map image.

9. A system for displaying map information on a portable computing device, comprising:
-
a map database that contains data representing a geographic area that includes a road network; a positioning system that determines a location of the portable computing device in the geographic area; and a map display application that accesses the data in the map database to generate a map image around the location of the portable computing device, wherein the map display application presents a sequence of alternating images on a display screen of the portable computing device when the portable computing device is approaching a location at which maneuvering guidance is to be provided for following a route, wherein the alternating images include an overhead view map image and one of a perspective view map image and a stylized image of an upcoming maneuver, and wherein one of the alternating images is presented at a time. - View Dependent Claims (10, 11, 12, 13)
