The vehicle 10 comprises a controller area network bus (CAN-bus) 30, an on-board diagnostics (OBD) system comprising a data port at a first OBD connector part 32 provided on the CAN-bus. The telematics system 34 comprises a basic security system 12 providing a first and limited set of functionalities and a telematics device 36 which is connected to a second OBD connector part 38 which in turn is connectable to the first OBD connector part 32. The telematics device 36 comprises a controller 41, a second wireless transceiver 40 which is connected to controller 41 and which, in use, is in data communication with the first wireless transceiver 24 of the security system 12. A means in the form of a GPS receiver 42 is connected to the controller for providing a second set of functionalities not included in the first limited set of functionalities. A third wireless transceiver 44 is connected to the controller 41 for enabling wireless communications with a remote backend 46. ## Claims ### Claim 1 A telematics system for 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 and a vehicle security system comprising a first wireless transceiver and which vehicle security system provides a first and limited set of functionalities, the telematics system comprising: 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; 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 provided by the vehicle security system; and a third transceiver connected to the controller for enabling wireless communications with a remote backend. ### Claim 2 (depends on 1) The telematics system of claim 1 wherein the third transceiver comprises at least one of a Sigfox, LTE, GSM, 4G and 5G transceiver. ### Claim 3 (depends on 2) The telematics system of claim 2 wherein the third transceiver is configured to communicate with the remote backend via the internet of things (IoT). ### Claim 4 (depends on 1) The telematics system of claim 1 wherein the telematics device derives power for operation from a battery of the vehicle via the first and second OBD connector parts. ### Claim 5 (depends on 4) The telematics system of claim 4 wherein the telematics device comprises a local battery to power the telematics device in the event that the second OBD connector part is separated from the first OBD connector part. ### Claim 6 (depends on 1) The telematics system of claim 1 wherein the first and second transceivers are paired with one another and a secure data link is established between the first and second transceivers. ### Claim 7 (depends on 1) The telematics system of claim 1 wherein the means connected to the controller for providing a second set of functionalities comprises a receiver of a satellite-based radio navigation system and wherein the second set of functionalities comprises a position determining functionality. ### Claim 8 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. ### Claim 9 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.
