XM WX vs SiriusXM Aviation Weather?

[Ron B.]

So Am I to understand that with the SXM package we can turn off the subscription for up to six months (winter) without penalty and then return to service without an activation fee? Also I could not find (on Sirius site) what the activation fees were. Any help determining Sirius charges would be greatly appreciated as I finally got around to mounting my GXM42 today.
