Abstract
An accessory for an electronic device detects manipulation of a user input of the device and alters an operating parameter of the accessory in response to the detected manipulation of the device's controls. The accessory is preferably an FM transmitter designed to be coupled to a portable media player such that an audio signal from the player is broadcast by the accessory. The user controls of the player can be used to select a transmission frequency of the accessory. The accessory can also preferably control the display of the device such that an image corresponding to the selected transmission frequency is generated by the accessory and displayed on a screen of the player.
