I tried out the Beta 2.0 Voices Navagation.
I am very happy about the TTS abbreiviations.
I did have some problems. I unzipped all of the files over the old ones from the Beta 1 and ran the program as a standalone. I then tested entered a route and off I went. I recieved 2 crashes by the time I got from work to home (4 miles). There was no specific error message... just the windows generic "do you want to send blah blah blah"
I suspected that it might be becasue I copied over the old files so i started fresh and havn't had a chance to test. I will keep posted
