Can OnStar be used in a 2008 GMC Acadia SLT-2?
Yes, you should be able to just press the blue Onstar button and the vehicle will contact an operator and they will explain the different levels of plans. You should be able to go to www.onstar.com and put in your vehicles VIN and find available plans that way too.
I bought an 05 and it was still active, someone forget to terminate the subscription when they traded in the vehicle, I know I didn't want it and OnStar said they would handle it.
Yes. 2004 and newer operates on the current digital system. 2003 and older is analog. As others have said, just contact OnStar and set up your subscription. HTH. -Jim
