Well I have had so few accidents, none my fault that I don't think it's worth the trouble. Touch wood.
As GPS, I have 3 different map apps on my Samsung S4 active phone with voice directions. Works great with no need to look at the screen. Some times it I prefer a different route than suggested, it fun to ignore the direction as if it is the wife or girl friend LOL good that it eventually picks up the route your are taking
