I have seen this posted around, but wanted to see if others are experiencing it more now that the DNAs are getting a bit older.

When I hit spots with no cell coverage (parking garage, dead spot in town) my DNA will power off - even on a full battery. I can't power it back on unless I plug it into a AC outlet (the USB or cig litter charger in the car will not work).

It happens somewhat randomly - not every time from what I can tell, but enough to be annoying - particularly since I am out somewhere and don't have a wall outlet to plug into.

Anyone else have this issue?
