Although verizon navigator was a complete waste of money....When I had my Storm2 I at least had the comfort of knowing the navigator would continue running and not get me lost while the phone was doing other things.
It would be nice if the navigator would continue running if the back button or other key is accidentally bumped.
An audible warning is necessary when leaving a signal area and using navigation in an unfamiliar area.
When your screen has gone dark and you are driving along, waiting for a voice to tell you when to turn... you can become quite lost before you realize your signal is gone.
I do have a suggestion for an app though.
I've seen apps that supposedly detect traffic cams, why no radar detector?
