Abstract

A navigating method for a cell phone with a positioning device and the apparatus thereof are described. The longitudinal and latitudinal coordinates of a guiding mobile in a global positioning system (GPS) are sent to a guided mobile via a short message service (SMS). After decoding the short message contents, the longitudinal and latitudinal coordinates are obtained by the guided mobile. And a navigation application is wakened and launched to perform a navigation function by establishing the longitudinal and latitudinal coordinates as a navigation destination.
