Abstract: An adapting device for adapting a first portable media player to emulate selected mechanical and electrical characteristics of a second portable media player includes a housing having first and second connectors. A signal converter is operatively connected to the first connector and the second connector for converting a first signal representing at least one command received over the second connector into a second signal representing the command to be transmitted over the first connector. A mechanical interface is configured to interconnect the second connector with an accessory device that accommodates a second portable media player having the second connector.
