1. A method of automatically updating a set of geo-fences stored on a storage device of a telematics system on a mobile asset that is wirelessly linked to a central station, wherein the telematics system has a location device and wherein at least one of the geo-fences of the set of geo-fences stored in the telematics system memory is a trigger geo-fence, comprising:

  • determining the present location of the mobile asset with the location device;

    determining at the asset whether the present location of the mobile asset is located within the area defined by the trigger geo-fence stored in the telematics system memory; and

    updating via the wireless link the set of geo-fences stored in the telematics system memory based upon the present location of the asset and the trigger geo-fence within which the asset is located, by replacing at least one of the geo-fences stored in the telematics system memory with replacement geo-fences from a library of geo-fences stored on a storage device at the central station, wherein the replacement geo-fences are selected such that at least one geo-fence in the telematics system memory is a trigger geo-fence after the replacement geo-fences replace part of the set of geo-fences stored in the telematics system memory, if the mobile asset is located within the area defined by one of the trigger geo-fence stored in the telematics system memory.
