Sirius Radio/Lowrance LWX-1 help!

[ahlangle]

Lowrance LWX-1 with Sirius Radio on HDS-7 or 8 unit, can't get the satellite radio to play.
The tuner radio, iPhone through USB cable, and CD players all play audio, and my Sirius subscription for GPS and weather work great.
I can even see the Sirius radio stations and the song it is playing on my screen, but for some reason it will not play over my speakers.
The auxiliary cable is good.
The unit under my console "navico interface module" obviously has the "power" light on, but the "status" light off.

This has happened before and spontaneously come back on. I'm thinking it's a simple menu or selection issue.
I don't want to get too deep in there and mess up my weather and GPS connectivity which are good.
Any help much appreciated.
