I was just in contact with Onstar and they told me this was not even possible. They told me Onstar could not be activated unless someone pressed the blue button. Been waiting 4 months for this truck, ordered 3/5/2020. All I know is that its been in transit for a week and I live 4 hours from the Plant.
I ordered a GMC AT4 Carbon Pro with the 3.0 diesel on 3/5. Just found out today that my Production target week is 6/15. So much for the 6-8 week lead time I was told when I ordered.
