I tried out the latest Beta version this morning on my way to work. I took a different route than the program chose. It rerouted me alright, but gave me about 5 or 6 audible rerouting messages in a 10 second period. It did miss the voice prompt at the first turn after the reroute. Also, when I turned on the last road in front of my work-it didn't have me on the road. It thought I was on a side/local road and kept giving me the audible rerouting message until I deleted the route. Overall, it worked very well until I took a different route than was chosen. Good Job!!!
