heard allot of people wondering which version they have and don't know how to check it.
To find out, long press the call button on the rear view mirror till you hear your version.
(I wonder if owners of previous Onstar version can upgrade?)

The way I understand it, Onstar Version 9.0 has a hardware difference that prevents 2010 and older models from using it. For past hardware upgrades it was possible to install upgrade hardware aftermarket but I doubt it would be worth the cost.
