How do I setup the app on a previously owned car? I have installed the app and created an account, do I have to launch OnStar to see any options within the app?
I believe you have to tell GM that you own the car now.
There is a way to do it, but I forget how. Contact Us | GM Owner Centre | GM Canada
I kept getting recall notices for a car I had sold 10 years previous and the notice told me how to do it.
