You have to get a digital upgrade to be able to use it properly. Contact OnStar. The older versions are on an old system they don't use anymore.

I was told by onstar that they no longer update from analog to digital. And my yr model doesn't have bluetooth. So i have 2 more questions...is it hard to just get a newer onstar and install it? How can i make use of the mic and add bluetooth to my vehicle?

Onstar will advise you to contact the dealership for upgrades
