Abstract: This present disclosure provides a GPS device for displaying traffic conditions and method thereof. The GPS device defines turn distance ranges according to GPS navigation information. When running into the defined turn distance range, the vehicle turns on a video device and turn signal lamps automatically, and displays the video feed provided by the video device. When passing by the defined turn distance range, the vehicle turns off the video device and the turn signal lamps automatically.

Abstract: A navigation method of the mobile device, wherein the mobile device comprises a GPS unit, the step comprising: receiving a message sent by an inviter mobile device; identifying whether the received message is an appointment message according to a message type flag in the message; determining an appointment location in the appointment message according to an address flag in the message; acquiring a map of the area including the location of the mobile device and the appointment location via the GPS unit; displaying the acquired map. A mobile device with navigation function is also provided.

Abstract: A navigation method of the mobile device is provided, wherein the mobile device comprises a GPS unit, the step comprising: receiving a message sent by a requester mobile device; identifying whether the received message is a route inquiry message according to a message type flag; determining a departure location and a destination of the inquiry route segment in the route inquiry message according to an address flag; acquiring route information between the determined departure location and departure of the route inquiry segment according to a GPS unit; generating a reply message including the acquired route information, and sending the generated reply message to the requester mobile device. A mobile device with navigation function is also provided.

Abstract: This present disclosure provides a GPS device with security function and method for the same. The GPS device includes a communications unit configured to transmit communication data between the GPS device and at least one external controlled device, at least one motion sensing unit, the method includes steps of: detecting current motion state of a vehicle, and obtaining sensing information; generating a first control signal to an external controlled device, when determining the vehicle is in a defined particular motion state; transmitting the first control signal to turn on the controlled device through the communications unit; generating a second control signal to the controlled device, when determining the vehicle isn't the particular motion state; transmitting the second control signal to turn off the controlled device through the communications unit.
