A telematics system for a vehicle

A vehicle comprising:

• a controller area network bus (CAN-bus);
• an on-board diagnostics (OBD) system comprising a data port at a first OBD connector part provided on the CAN-bus;
• a vehicle security system providing a first and limited set of functionalities and which vehicle security system comprises a first wireless transceiver;
• and a telematics device connected to a second OBD connector part which is connectable to the first OBD connector part, the telematics device comprising:
• a controller;
• a second transceiver connected to the controller and which, in use, is in data communication with the first wireless transceiver;
• means connected to the controller for providing a second set of functionalities not included in the first limited set of functionalities;
• and a third transceiver connected to the controller for enabling wireless communications with a remote backend.

A method of upgrading a vehicle security system comprising a first wireless transceiver and which system is deeply concealed in the vehicle to a vehicle telematics system providing more functionalities than the vehicle security system, the method comprising:

• connecting to an on-board diagnostics OBD port on the vehicle a telematics device;
• the telematics device comprising a second wireless transceiver and a third wireless transceiver;
• pairing the first and second wireless transceivers to enable data transfer between the vehicle security system and the telematics device;
• and
• configuring the third transceiver to enable data communications between the telematics device and a remote backend.
