I used to have Onstar on my GMC, but when I traded for a new Dodge truck I had to give it up. I didn't use it a lot but it was sure nice when traveling, I really had to give it a lot of thought as to wheather I could live without it or not. I usually find myself in places where there are no "places", if you know what I mean Also miss XM, the Sirius radio is no comparison in my mind.
