I have used ridewithGPS in the past for their audible turn by turn cues. I have just downloaded the cycle.travel app (iOS) and it isn't clear to me if the turn cues are audible and/or need a setting change to enable them.

It has been raining here and I haven't gotten out on my bike to test this. I will on Monday, but wanted to ask about it before I try it in case there is something I need to know before hand.
