Voice navigation not working on HTC One M8??!!

[ddetmer222]

Does any one has trouble getting the voice navigation to work on HTC One M8? I'm trying to get it work to speak Chinese for my mom, but nothing come out. So, I changed the language to English and make sure to take off the mute, and yet there is no sound but the navigation is taking us to the destination. Does HTC One M8 come with the voice navigation? I have no knowledge of working with Android phone as we are all Apple users. any help is appreciated!!
