Docking unit and vehicle power adapter with frequency modulated audio signal injection for connecting portable media player and/or communications device to vehicle FM radio and audio system for playback of digital audio broadcast stream
A cigarette lighter adapter (CLA) is provided with a main body configured to be connected at one end thereof to a vehicle cigarette lighter socket or auxiliary power socket. The main body of the cigarette lighter adapter is also connected to one end of a coaxial cable. The other end of the coaxial cable is preferably terminated with a standard low cost DC connector for connection to a portable media player (e.g., with integrated or separate satellite radio receiver) or other content source that provides a frequency modulated (FM) radio frequency signal with audio content onto the coaxial cable 60. The FM signal is amplified by an amplifier in the main body of the CLA and then injected into the vehicle power system through the contacts in the mechanical housing of the main body and the vehicle cigarette lighter socket.
