Samsung Transform Ultra works as a phone, I haven't tried it as a music player since I have Sirius XM on the car.
On 2012's the Connectivity package comes with the Cruise Control, if you don't have CC you don't have Connectivity, and vice versa. Since CC is needed for Select-a-tune, I had to have it... the connectivity turns out to be a nice free bonus, is the way I look at it.
As for the "download available thru Onstar" thing, wow, that really sucks. I mean, OK, I already had Onstar crammed down my throat by the dealer, so it's too late for me, but plenty of other paranoids were lucky enough not to have the dealer do them that "favor". But now in order to maintain the on board devices, we have to hook up with evilcorp like it or not? Rant mode ON! Is there an alternative, like downloading something to a flash drive?
