A few interesting observations I have made regarding the NBT:
- Every 10 minutes, the traffic data (colored lines on the map) goes away for about 1 second and is refreshed. I guess it could be every five minutes, but I have only noticed the refresh at the 10 minute mark.
- The traffic incident reports are quite helpful, especially because it indicates accidents and their point on the map. I don't remember how good this was on the CIC Nav?
