I decided to spend more time testing the navigator today. I have a standalone GPS, the problem is it's never around when I need it and when it is in my vehicle I always have to remember to lock it. I live in a Montana mountain town and Verizon coverage is excellent in each town and spotty to no coverage in between. I driven these roads thousands of times so really no need for GPS.
Well today I had to make a short 90 mile trip to the next town most of which there isn't cell coverage. I turned on the navigator and said my destination, as I entered the canyon, to my surprise, the map was there. The cell signal was off but the map kept refreshing the route.
All of a sudden a full on winter blizzard hit and it was a complete white-out. I had to slow down to less than 50 mph and visibility was 20 yards. It was extremely difficult to tell where the next curve in the road was. Then I looked at the Droid navigator and there it was - like radar, showing me the whole layout ahead of me. For travelers in inclement weather, this application is priceless. Just remember to enter your destination and Google Maps Navigation will download a cached file even though cell coverage is gone. Awesome app!
