Frequently Asked Questions
What hardware do I need to access SiriusXM Marine Weather?

You will need a chartplotter/MFD and a compatible receiver from one of the leading marine electronics brands. Our marine service is available on B & G, Furuno, Garmin, Lowrance, Raymarine and Simrad products using compatible marine receivers.

Can I suspend my service when my boat is out of the water or not in use for a period of time?

We allow customers to “Seasonally Suspend” service at no charge for up to 6 months when their boat is not in use.

How can I get SiriusXM Satellite Radio (audio service) on my boat?

You can add SiriusXM Satellite Radio to your SiriusXM Marine Service. If your hardware is compatible, you can access and control satellite radio through the same equipment that you access our weather service. You can also purchase a separate SiriusXM Satellite Radio or tuner and an audio subscription and connect it to the stereo head unit audio system on your boat.

If it has been more than a month since I last used my SiriusXM Marine receiver, what should I do to ensure that it works when I need it?

You can send a refresh signal to your receiver at siriusxm.ca/refresh on your smartphone or computer or call 1-844-823-0843. You will need your Radio ID/ESN.
