7) Please provide a technical description of operation/function of the FM coupler. Please upload this information as a separate exhibit (operational description) to ensure proper treatment of confidentiality. A7) The Sure Connect FM Coupler is designed to deliver the FM modulated signal from the XM Radio receiver to the vehicle FM radio by means of capacitive coupling. The Sure Connect clips to the vehicle‘s whip antenna, or in the case of an in—glass FM antenna, to an adhesive backed clip that is situated on the glass in close proximity to the vehicle‘s FM antenna. The FM power level is set such that radiation from the shielded cable is minimal and within FCC limits, yet the power available through the coupler is sufficient to provide good reception of the FM modulator signal. There is no need for confidentiality of this description since FM couplers are currently on the market. The FCC has previously certified numerous XM devices using the SureConnect FM coupler (such as in the Audiovox XPress (FCC Identifier BGA—XMXPO3, granted August 25, 2006) and the Delphi Roady XT (FCC Identifier RS2SA101778, granted August 25, 2006).
