First let me say that I have read countless threads in forum and wiki to no avail. Using iPhone 5, Waze has developed voice navigation problems. Most of the time when I select a route and click Go instead of opening voice instructions I get a voice question: "How can I help" Unless I am going to work or home there is no voice command to actual destination so I remain silent. The voice repeats saying I can't hear you and then says "cancelled" and no directions follow. If on the way home I reply "Drive home" and the response is "I couldn't hear you say again". This repeats and finally voice says "cancelled".
Sometimes this happens and then somewhere in the middle of the route the voice commands pick up. Makes no difference whether bluetooth is on or off.
When I first started using Waze everything was great. I even wrote raving review in iTunes.
It's to the point that my wife will not let me use Waze when she is in the car and I'm left with Apple Maps or Google. I want Waze back.
