I have an xm unit w/1920 navnet vx2 plotter. it is nice but only for weather; thunderstorms and storm fronts. It really sucks for the sea temps. Any sea surface company will tell you how unaccurate it is. Trust me from experience i chased the break last year almost all the way to the norfolk and still never found it. According to the screen it was in the Washington-where??? It is not totally worth the price.
We have used a Garmin 478 with XM weather for several years. We have the Master Mariner package and I have to say that it is "totally worth the price". To use the Mastercard commercial, the value of missing one, or two, or whatever thunderstorms is "priceless". Our unit has shown us far more weather info than all other sources and allowed us to safely get from A to B while avoiding bad storm cells. It has also allowed us to stay out and fish, when we could clearly see where the cells were headed.
This doesn't even address the ability to get 'close-to-real-time' updates from the weather buoys.
Never bought it for SST info. Lots of free, and paid, services to provide that info.
Sorry if someone told you it had any value for SST. And Sirius wx is not any better. But the answer is simple - cancel your XM service.
