The main objective of this paper is to analyze the type of antenna which is connected to the car and to provide the necessary action will be performed for the power supply unit. There will be a several decades to fit commercial vehicles and private cars with radios to receive national broadcast programs. The performance of these radios has now become more critical in view of the demand for high fidelity audio, the increasing number of local radio stations. Either Active Antenna or Passive Antenna will be connected with the car for FM Radio reception. The type of antenna will be detected by the current response of the device. This will be handled by the current sensing circuit which is in the main board and microcontroller in the front board. The corresponding information will be displayed in the display unit. All of these process will be handled in the Audio Head Unit (AHU).
