Another mapping/navigation app I have used is OsmAnd (Open Source). One nice thing about OsmAnd's voice prompts is that if two turns are fairly close together (say 50m apart) it will say something like "In 100 meters make a right then in 50 meters make a left".

Aside from fixing the 3 second pause between a turn direction and a street name (e.g. "make a left" ... <3 second pause> ... "on Mohawk Road") that I'm experiencing this feature would make Waze just about perfect.
