In this case, the CDMA chip 322 is connected to the voice processing unit 560 of the vehicle navigation information providing system 500 and transmits the received voice input command to the voice processing unit 560.

When the emergency rescue key is selected by the driver or the user, the navigation terminal 300 requests an access to the emergency center and transmits an emergency rescue message indicating that an emergency situation has occurred. In this case, the emergency rescue message is transmitted by using the SMS protocol which has a higher reception rate than a general telephone communication service without using general data communication.

In the above, the internal configuration of the vehicle navigation apparatus has been separated and described, but this is not hardware separation, but logical separation.

In addition, although the CDMA chip 322 is described as being mounted on the navigation terminal 300, the CDMA chip 322 is not provided by electrically connecting the separate wireless communication terminal and the navigation terminal 300. You can also perform home network control functions.

In addition, considering that a request signal for controlling the home network generates a cost for sending an SMS message by setting up a home gateway and a wireless channel provided in the home network system via a mobile communication network, the vehicle returns to the home mainly. The home network control function is activated at home.

However, the home network control function may be performed even if the vehicle is not located near the home but at a long distance.

For example, even if it is located far away from home, such as a summer resort, the home terminal can be easily controlled from a long distance by setting a home gateway and a wireless channel of a home network system via a mobile communication network using a navigation terminal provided in a vehicle.
