Just to confirm, is it possible to have Bluetooth if OnStar is physically not present? If so, what are all the components necessary? For example, do you still need a special rearview mirror, or does a standard/generic mirror work?

 

I have and use my bluetooth but do nto use the OnStar...however I think.. that the special mirror is also used by the bluetooth.. but i am not 100% sure of this...

 

Thanks, I clarified the question...I know you can use bluetooth if you just don't subscribe to OnStar, but my HHR physically does not have OnStar. On the original build sheet, it was deleted because it was a fleet vehicle. However, the build sheet does say that it has bluetooth.

 

You must have OnStar to have GM bluetooth.
