Abstract

A vehicle communication device that is engageable to a vehicle, e.g., by a vehicle license plate fastener and/or within an OBD communication device, for interfacing a vehicle electrical system to a V2X data stream. A micro computing unit (MCU) is disposed within the device, defining a processor and a memory. The MCU is configured to derive information from the V2X data stream. An antenna circuit is disposed within the housing, in communication with the MCU, and configured to receive and communicate the V2X data stream to the MCU. A vehicle electrical system connecting circuit is also provided for communicating the information derived from the V2X data stream to the vehicle electrical system.
