Navigation device with adjustable data transmission

1. A system for determining the location of a navigation device comprising:

a navigation device, comprising:

a location determining module comprising hardware and logic to:

generate first data relating to a first geographic location of the device based on a first received navigation data;

generate second data relating to a second geographic location of the device based on a second received navigation data;

receive a user input corresponding to a threshold transmission value representing a frequency at which the first geographic location is to be transmitted over a communication interface,

wherein the communication interface provides power to the navigation device;

calculate a change in a geographic location of the device based on a difference between the first generated data and the second generated data at the device; and

transmit the second generated data over the communication interface when the calculated change in the geographic location of the device exceeds a threshold geographic change value representing an amount of change in the geographic location of the device, wherein the threshold geographic change value is selectable from a plurality of threshold geographic change values; and

a host computing device in communication with the navigation device, comprising

a GPS device driver to allow a data stream application to communicate with a host universal serial bus controller,

wherein the data stream application is to receive a constant stream of data including data relating to the first geographic location of the device from the GPS device driver;

when there is no change in the geographic location of the device and when there is a change in the geographic location of the device.

2. The device of claim 1 , wherein the communication interface is selected from the group consisting of universal serial bus (USB), wireless interface and wired interface.

3. The device of claim 1 , wherein the location determining module transmits the data in accordance with a serial communications protocol.

4. The device of claim 1 , wherein the location determining module generates data independent of whether an amount of change in the geographic location of the device exceeds the threshold value.

5. The device of claim 1 , wherein the device receives power to power the device from another device over the communication interface.

6. The device of claim 1 , wherein the location determining module receives data to determine the location of the device which is selected from the group consisting of global positioning system (GPS) system, terrestrial-based system and satellite-based system.

7. The device of claim 1 , further comprising a display device to display information and an input device to allow input of information.

8. A method of determining a location of a device comprising:

generating first data related to a first geographic location of the device;

generating second data related to a second geographic location of the device;

determining, at the device, a change in a geographic location of the device based on a difference between the first generated data and the second generated data;

receiving a user input corresponding to a threshold transmission value representing a frequency at which the first geographic location is to be transmitted over a communication interface,

wherein the communication interface provides power to the navigation device;

transmitting the second generated data over the communication interface when the change in the geographic location of the device exceeds a threshold geographic change value representing an amount of change in the geographic location of the device, wherein the threshold geographic change value is selectable from a plurality of threshold geographic change values; and wherein the communication interface provides power to the device; and

transmitting a constant stream of data related to the first geographic location of the device between a GPS device driver and a data stream application associated with a host computing device when there is no change in the geographic location of the device and when there is a change in the geographic location of the device, wherein the host computing device is communicatively coupled to the device.

9. The method of claim 8 , further comprising transmitting the data in accordance with a serial communications protocol.

10. The method of claim 8 , further comprising receiving data to determine the location of the device selected which is selected from the group consisting of global positioning system (GPS) system, terrestrial-based system and satellite-based system.

11. A non-transitory computer-readable medium storing instructions that, when executed by a controller, causes the controller to:

generate first data related to a first geographic location of a device;

generate second data related to a second geographical location of the device;

determine, at the device, a change in a geographic location of the device based on a difference between the first generated data and the second generated data;

receive a user input corresponding to a threshold transmission value representing a frequency at which the first geographic location is to be transmitted over a communication interface,

wherein the communication interface provides power to the navigation device;

transmit the second generated data over the communication interface in response to the change in the geographic location of the device exceeding a threshold geographic change value representing an amount of change in the geographic location of the device, wherein the threshold geographic change value is selectable from a plurality of threshold geographic change values; and wherein the communication interface provides power to the device; and

transmit a constant stream of data related to the first geographic location of the device between a GPS device driver and a data stream application associated with a host computing device when there is no change in the geographic location of the device and when there is a change in the geographic location of the device, wherein the host computing device is communicatively coupled to the device.

12. The non-transitory computer-readable medium of claim 11 , further including instructions which when executed cause the controller to transmit the data in accordance with a serial communications protocol.

13. The navigation device of claim 1 , wherein the communication interface provides power to the navigation device via a wired connection.

14. The navigation device of claim 1 , wherein the location determining module receives a signal to set the threshold value representing the amount of change in the geographic location of the device.
