The SIRIUS radio plugs right into the back of your Sony stereo, and sends channel information, including channel name, artist name, program name, and song title, to your stereo's display. The radio also features a built-in pass-through connection, so you can keep your Sony CD changer hooked up. The package includes a roof-mount SIRIUS antenna.
