Abstract

A direction indication device of a global positioning system which is composed of a host having a voice device and a display panel. An exterior of the display panel is enclosed with a cover, on which an indication unit is installed and includes at least one illumination element. Each illumination element represents a direction indication. An interior of the host also includes a navigation module which produces a navigation signal and a direction indication module which produces an indication signal on the indication unit. After the direction indication module has received the navigation signal, the illumination element representing the direction will produce light to represent the direction indicated by the navigation signal, such that a driver can be indicated the direction on the display panel without watching at the global positioning system.

Claims

1. In a global positioning system comprising a host having a side provided with a display panel, said display panel being enclosed with a cover, a navigation module provided in an interior of said host, and a voice device provided in said interior of said host, the improvement wherein an indication unit is provided on a top of said cover and has three illumination elements, said three illumination elements being arranged so that a first one of said illumination elements being positioned at a left side of said top of said cover, a second one of said illumination elements being positioned at a right side of said top of said cover, and a third one of said illumination elements being positioned between said first and second ones of said illumination elements, and when a driver configures a route and a destination for navigation through said display panel, said navigation module will search for satellites, plan said route and produce a navigation signal on said display panel to show a direction indication such as a left turn signal, a forward signal, or a right turn signal, said voice device produces voices to inform said driver simultaneously corresponding to said direction indication on said display panel thereby allowing said driver to know said direction indication through said voice device at the same time, and said navigation signal is transmitted to a direction indication module which produces an indication signal on said indication unit to cause a corresponding one of said illumination elements to flash, thereby notifying said driver of said direction indication by means of an image on said display panel, voices from said voice device and flashing light for a corresponding one of said illumination elements at the same time.
