  "textContent": "An on-board unit (10) for a vehicle is disclosed. The unit includes a primary communication system (11), the primary communication system being adapted to communicate with a remote location, and being further adapted to detect a stolen condition or receive an indication of a stolen condition. The unit also includes a process for determining whether communication with a central location can be effected. A secondary communication system (13) is provided, the secondary communication system (13) transmitting a signal including an identification of the on-board unit (10) when communication with the central location cannot be effected. This signal is received by a receiver, which is in direct or indirect communication with the central location, so that the central location can take the appropriate steps to recover the vehicle which includes the on-board unit that is emitting the signal.",
