I've been having issues with Waze not having voice navigation as well! However, I think there is a solution (see below). Btw, I recently got a new phone so I was perplexed why the Waze app wasn't saying anything on this new device.

So I think what you mean is that under Settings>Speech>Read aloud incoming text messages.... I changed it to "wired headset only".
There is a bluetooth issue with the app so it is trying to send its voice navigation to bluetooth.
I will test whether the app starts doing voice navigation. So far, it looks like it is working as the beeping indicating navigation has started is working but I'm inside so I will test it when I drive home.
