You probably have in your 2016 GMC a settings app on your interface page. There is a video on youtube showing you how to adjust it. Go here to see it: https://www.youtube.com/watch? v=PB43m5hZMoo

The voice volume is probably just turned down so low you can't hear it. There is a voice level control in the menu you can use or, when you are coming to a turn as indicated by the unit, turn the volume up but this needs to be done while the voice is giving you a command.
