I think i received a similar offer and checking the longer fine print it's only for the once car and you have to pay extra for another SIRIUS device (like my receiver). They screwed up the 90 free period I can't count on them to actually do what they say they'll do so
Yes as I have no confidence Sirius would ever put the service on my car (GM apparently had the OnStar working fine and I extended that, but never had the Sirius working) and while my Sony receiver has an option, I don't listen to music enough to warrant the extra cost ... besides My Momma always...
I was supposed to get SiriusXM when I purchased my Pre-owned GM car from a GM dealer but the only stations that came up on my Sirius button was "Canadian Stations" <_< I think the one time I tried to listen to it while the "free" trial was on there was some news from the CBC ...
So, no I have...
