To use SiriusXM on a Garmin Marine Chartplotter, a compatible weather antenna will need to be connected to the device. Refer to the owner's Manual for the chartplotter to determine which SiriusXM antenna is required.

SiriusXM weather and radio are subscription-based services through the provider, SiriusXM. To activate a subscription, use one of the following methods:

If a GXM is being used, visit the SiriusXM Marine webpage
- Or call 855-796-9847
If any other weather antenna is being used, visit the XM Marine webpage
- Or call 800-985-9200

Before contacting SiriusXM, the Weather ID and Radio ID of the weather antenna will need to be determined. These numbers can be found on the bottom of the antenna. These numbers can also be found in the menu of the chartplotter or sounder the antenna is connected to. Refer to the Owner's Manual for information on where to find the Weather and Radio ID in the chartplotter or sounder.

If you are using a GDL 30A, there will be a Weather ID and a Radio ID that are different. If a GXM 30, GXM 40, GXM 51, GXM 52, GXM 53 is being used, there will only be one ID that is used for both Weather and Radio.
