Abstract

A method apparatus for orienting a map display in a mobile or portable device. An electronic compass is integrated with a hand-held portable or mobile mapping device and an electronic compass bearing is used to calculate an offset value with respect to the map default orientation. The map is thus reoriented in the display to the direction of the device. In an alternative embodiment, a GPS receiver is also integrated with the device. A heading fix is calculated from two or more GPS position fixes to determine orientation of the device. When a heading fix is unavailable, such as at initial start-up of the device, a compass heading is used in lieu of the GPS heading fix to orient the map on a display.
