Hey folks. Newbie TourX owner here... (Love, love, love the car!) I'm coming up to the end of my one-month trial of a variety of OnStar and connectivity services and I'm trying to figure out which, if any of them, I should renew or cancel. I've never had a vehicle with OnStar before, and it seems like a lot of the features offered simply duplicate things I can get using my own navigation services on my iPhone. (I've looked at the various plans that are offered and there's some overlap, it seems, which leads to my confusion.) I don't need "vehicle locator" or "instant diagnostics." And why would I need "turn-by-turn navigation" from a separate OnStar plan? If I put in a destination using the built-in nav in the vehicle, aren't I getting that info already? I assume that feature doesn't go away if I cancel the "Buick Connected Services Trial." Similar question with "Connected Navigation," which touts real-time traffic info. But don't we already get real-time traffic info through Sirius/XM? Does THAT go away if I cancel the Connected Services Trial? I do plan to re-up a data plan for the mobile Wi-Fi hotspot in the car. It appears that that's a separate feature not connected to OnStar or the other services. But when I compare plans, the list of features seems to indicate that unlimited data only comes with an Unlimited Access plan ($39 a month), or the Unlimited Access + Safety and Security plan (for $59 a month). I guess the bottom line is this: If I cancel these trial plans outright, and keep only the WiFi hotspot data plan and the basic OnStar service that lasts 10 years, what am I really giving up? ANY insights would be helpful before I call OnStar.
