Here are your questions and my answers:
- When you subscribe does the Weather menu option automatically become active? YES
- How good is the system at allowing you to avoid rain cells (this would be my main reason for subscribing) in the weather map mode? Fairly good at showing you the areas of weather. Radar is updated roughly every 5 minutes
- How much detail do you see on the weather map screen? It is easier to see the edges of the weather when zoomed out. Zooming in tight, you tend to have less situational awareness.
- Can you zoom the weather map screen just like you can the navigation screen (The navigation book shows the weather map showing about 2/3 of the entire US. That would be totally useless at avoiding rain cells in the local area)? YES
- Does the weather screen blank or just not update when you are not in view of the satellite (tree problem)? Doesn't update
- What does it cost to subscribe to XM radio and weather? Trick question, it varies depending on your negotiating skills
- How do you go about subscribing (what number to call, how do you identify the XM radio you want to activate etc)? Some will say to activate it on SiriusXM.com, others call 1-866-635-2349. In any case, you get your XM radio ID or ESN off of the menu on the bike
- The Navigation manual says XM radio and I assume that means XM weather maps are only available in the 48 contiguous states. What happens when you cross the border into Canada? Does the radio and weather maps just quit? Can't help you, haven't been up there
- Is there anything that I should know that I am not asking? Can't think of anything
- Do you feel the XM weather maps are worth the cost of subscribing to the service? Do you find it of help in avoiding rain cells? I do feel it is worth it. Keep in mind that no radar or wx depiction is going to be perfect. That is the nature of radar. It will give you a fair idea of the area to avoid, but if you expect it to be exact down to the line, you will get wet. I've read where people are upset because they got wet when they were skirting the green, but not in it. Nature of the beast.
