My husband, who is much more savvy in the realm of cars, tells me this vehicle is basically a GMC Envoy. Hence it is equipped with Onstar. We haven’t felt the need to pay extra for those bells and whistles so we never activated it when we bought the car used. I’ve been really content with all the extras it has, like the heated seats in winter. No real need for that in the summer. Air conditioned seats might be a tad more appropriate given our climate is warm more often than it seems cold.
