How do I activate my Sirius Marine Weather service?

After your receiver is installed, connected to your display product and powered up, you or your dealer can dial 1-855-796-9847 to activate the service. Be sure to read the complete terms of our Customer Agreement first.  To activate, please have your billing information, subscription preferences and the Sirius ID# for your receiver ready. Your service can be activated within minutes. (Not sure where to find your Sirius ID? It's accessible through the user interface on your weather viewer display.)
