Is there a way to make this unit 'onstar' Compatible?
My husband says his 2010 Cobalt has to have a specific stereo setup or he'll lose his 'onstar' capabilities. I think there should be a way to keep 'onstar' without having to buy an expensive stereo. I just need to know if there is a wiring harness or add on that will make this unit be compatible if it's not already.
