I recently hooked up a Garmin GXM 51 to a nmea 2000 network to interface a Garmin gps for the xm/sirus weather service, ect. I was given a fusion 600 series radio that says Sirus ready. The GXM 51 has a second cord on it for audio, it also includes a connector to take the audio cord and make it into traditional red/white aux jacks. So if I hook up the red white, I can hear the satellite service basic channel, playing it through the aux on the Fusion stereo but I am unable to change the stations on the satellite. Anyone know how this connection is done? Is there a special adapter of tuner needed. I notice the fusion has a cord for satellite in, but I have no idea where to find the connector for it even after some research. Thanks for any help.
