The present invention relates to a method for operating a communications accessory device (1) for a motor vehicle (2) having an ignition variable between an "ON"-state and an "OFF"-state, wherein the device (1) comprises a permanent power supply line input (12) and an ignition sense line input (13), wherein the device (1) further comprises a control logic (14) directly or indirectly connected to both inputs, and wherein, when not installed, the power supply status (6) of both inputs is "LOW" and, when properly installed in a motor vehicle (2) the power supply status (6) of the permanent power supply line input (12) is permanently "HIGH" and the power supply status of the ignition sense line input (13) is "HIGH" when the ignition of the motor vehicle (2) is "ON" and is "LOW" when the ignition (8) of the motor vehicle (2) is "OFF". The inventive method comprises the following steps: individually detecting the power supply status (6) of the power supply line input (9) and of the ignition sense line input (13) and, in response thereto, at least setting a wrong installation status flag (15) when a power supply status (6) "LOW" of the power supply line input (9) is detected while a power supply status (6) "HIGH" of the ignition sense line input (13) is detected.
