The voice navigation method relates to a voice navigation device and a voice navigation method, which may be utilized in cooperation with the Satellite Global Positioning System. The method is used to broadcast a voice-guidance-item having higher requirement importance more preferentially than a voice-guidance-item having low requirement importance, even if the voice-guidance-item having low requirement importance is obtained when the voice-guidance-item having high requirement importance is still in progress.

A method for reminding of entering a target route is disclosed. First, the method provides a Point of Interest (POI) at a conjunction of the present route and the target route and sets the POI as a basic voice reminding point. Next, the method determines whether the actual distance between the present position and the basic voice reminding point is less than or equal to the voice reminding distance. Then, when the actual distance between the present position and the basic voice reminding point is less than or equal to the voice reminding distance, a voice reminding message is sent out as the reminding of entering the target route correctly.

The present invention provides a method for updating GPS ephemeris data, which is applicable to a navigation device containing a GPS ephemeris data. The method for updating GPS ephemeris data includes the following steps: first, the navigation device counting down a predetermined time; next, searching a GPS ephemeris data server through a network interface; then performing a download from the GPS ephemeris data server so as to update the GPS ephemeris data in the navigation device. Accordingly, the time required for updating ephemeris data is shortened.

A method for auto-writing into an address book is provided, the method including the steps of: first, receiving a target after the navigation device being started; then judging whether there is one of a plurality of addresses in the address book being located within a predetermined range around the target; thereafter, if there is one of the addresses in the address book being located within the predetermined range around the target, displaying one of the addresses for the user confirmation; finally, writing the user-confirmed global satellite positioning coordinates of the target into the one of the addresses.
