Abstract: A digital radio receiver system is provided as a single module for retro-fit connection to the external antenna connector of a vehicle or the like. The system includes an antenna connected to a radio receiver which is configured to scan and receive digital radio channels through the antenna. There is also a wireless communications module for wirelessly transmitting to an external display and control unit information relating to the available channels and for receiving back a selected channel. A transmitter is provided for decoding a selected channel and transmitting it as a modulated signal down a wired feed from the eternal antenna connector to an analog radio head unit for output on a given channel. A renewable energy unit is provided on the module for powering the receiver, communications module and transmitter.

Abstract: A self-contained antenna module for attachment to a vehicle exterior, includes a connector for attaching to an existing wired feed connector to an entertainment head unit, a cellular communications module, e.g. a 3G/4G module configured to provide a local wireless internet access point, and a renewable energy source for generating independently of the vehicle's own power source electrical energy for charging an on-board battery which provides power to the cellular communications module.
