You can change it under the sat nav settings, or you can wait for the sat nav to ‘say’ something and turn it up with the volume know whilst its in that mode. You can see if a sat nav instruction is being read on the screen with a icon.
The volume is so easy to adjust as previously said,just put a destination into the sat nav,then drive and the moment it issues an instruction like roundabout or road junction etc,the volume control that is normally for the radio,becomes the volume control for the sat nav.
