6. An alert device as claimed in claim 3, wherein the alert application monitors said location items within a range of the location of said vehicle based on relative movement of said vehicle to said location items.

7. An alert device as claimed in claim 6, wherein said range is defined by regions of a hierarchical region tree, and the position of said regions in a region stack maintained by said alert application, said position being determined by said location data.

8. An alert device as claimed in claim 7, wherein said relative movement is determined as one of approaching, receding and indeterminate.

9. An alert device as claimed in claim 2, including a voice processor for generating an audio announcement as said notification in response to said alert data.

10. An alert device as claimed in claim 2, including LEDs driven by said alert data to provide said notification.

11. An alert device as claimed in claim 1, wherein said alert data activates a component of said vehicle such as at least one light or an immobiliser.

12. An alert device as claimed in claim 1, wherein the communications receiver uses a wireless communications protocol, such as POCSAG or GSM/SMS, to receive said file fragments.

13. An alert device as claimed in claim 1, wherein said device is remotely configured by a user accessing a server, such as a web server, and defining the application, configuration and/or data files to be sent to said device in said fragments.

14. An alert device as claimed in claim 1, wherein said file fragments are broadcast by a transmission system.

32. A server transmission system for generating and transmitting file fragments for a device as claimed in claim 1, 15 or 25.

33. A server transmission system as claimed in claim 32, wherein said fragments are broadcast to a plurality of said device.

34. A server transmission system as claimed in claim 32, including a server for providing a user interface allowing a user to submit instructions used to determine the application, configuration, and data files, to be sent to said device in said fragments.

35. A server transmission system as claimed in claim 32, including a server for providing a user interface allowing a user to submit a vehicle identifier, said system selecting said alert device on the basis of said vehicle identifier.

36. A handheld communications device for transmitting file fragments to a device as claimed in claim 1, 15 or 25.

37. A handheld communications device as claimed in claim 36, wherein said fragments are received by said handheld device from a server transmission system as claimed in claim 32, 33, 34 or 35 prior to transmission to said alert device.

15. An alert device, including:

a wireless communications receiver for receiving alert files for said device;

a positioning unit for providing location data representing the location of said device;

a microcontroller system for processing and storing said alert files, and performing an alert application defined by said files and using said location data to provide alert data corresponding to the location of said device.

16. An alert device as claimed in claim 15, wherein said application is performed automatically by the device without any user intervention or interaction.
