1. A recovery system for providing an activation message to a vehicle location unit associated with a vehicle, the system comprising:
- a vehicle location unit disposed in a vehicle;
a central station configured to transmit a first activation message meant for the vehicle location unit;
at least a first remote transmitting unit including;
a first receiving unit for receiving the first activation message meant for the vehicle location unit, a controller for processing the first activation message, and a transmitter configured to transmit a second activation message, using the processed first activation message, meant for the vehicle location unit;
at least a second remote transmitting unit including;
a second receiving unit for receiving the second activation message meant for the vehicle location unit, a controller configured to process said second message, and a transmitter configured to transmit a third activation message, using the processed second activation message, to the vehicle location unit;
wherein the vehicle locating unit receives the third activation message but not the first or the second activation messages; and
wherein the first activation message includes a first code representing a vehicle location unit identifier and a third code which adjusts a transmission schedule of the vehicle location unit.
