2023 GMC Suburban has a broken OnStar Modular.
Our Internet went out and so did all of the searches and maps. We called OnStar and were told to take it to the Dealer. We did and were told the OnStar Module is broken. It is on back order. No date ...
Do you have a part number for the new module? Mine is broken to and I am trying to find a new one and install it myself.
