Well after dropping my Sirius XM for the silverado they offered me a new deal $5 of month to steam online. Skeptical but I bought the idea. Anywhere my iPhone or the wife iPhone can reach a tower, I have SM radio in both my Silverado and my Equinox plus at home.
And added but unexpected benefit. Son-inlaw bought me something, some kind of transmitter, not sure exactly what, about $15.. Now when out in the chevelle, I have Sirius XM streamed to my iPhone and played though my original 66 radio speakers along with another music stored on my phone. Radio also still functions on AM/FM bands as it original did.
