Telematics Communications Unit (TCU) is an electronic device used in vehicles, which receives communication from other electronic devices, and then, interprets and disperses the data. This communication is done through CAN, the most common network found in all the cars. CAN acts as a bridge for communication between TCU and other electronic devices. TCU focuses on driver and passenger safety, provides real-time direction, gives traffic status, and supports emergency call facility in case of any accidents.
