Abstract: The present application relates to a communications accessory device, system and method for a motor vehicle having an ignition variable between an “ON”-state and an “OFF”-state, wherein the device and system comprises a permanent power supply line input and an ignition sense line input, wherein the device and system further comprises a control logic directly or indirectly connected to both inputs, and wherein, when not installed, the power supply status of both inputs is “LOW” and, when properly installed in a motor vehicle the power supply status of the permanent power supply line input is permanently “HIGH” and the power supply status of the ignition sense line input is “HIGH” when the ignition of the motor vehicle is “ON” and is “LOW” when the ignition of the motor vehicle is “OFF”.

Abstract: Systems and methods applicable, for example, in connection functionality. A device might, for instance, provide connection to one or more services via one or more devices. The device might, for example, detect a device offering one or more of those services. The device providing connection might, for instance, consider one or more priorities, connection disruption indications, and/or connection maintenance indications. The device providing connection might, for example, stop providing connection via one or more of the devices via which connection was being provided, and/or might start providing connection via the detected device.
