When you press the voice instruction button, do you hear a beep? If so, it is awaiting instruction, and the response voice could have the volume totally muted.
Try this: hit the voice command button, and repeatedly press the up arrow for volume control, and repeat "options" every 5 seconds.
If you hear nothing back, you either don't have voice commands, or something is wrong with the hardware.
I am pretty sure you need nav in order to have voice. But you don't have to have Assist activated.
