I have a 22 Blazer so yours should be the same: On your truck, disable AA. Go to settings, system, phones. If you only see your phone associated via AA (should indicate not connected), push the 'add phone' button and pair your phone. Now you have it paired via BT and independent of AA. You should now have a BT option on your main audio screen. If you need further help feel free to message me outside of this thread.
