So we took a 250ish mile trip from Cinci to Detroit over the weekend and used Google Nav to get us there and back. The wife and I each have a DROID and we switched back and forth between them whenever we felt like it. At any point during any of the navigation, either of our phone would suddenly "blank" out and then come back on. Almost as if someone hit the power button, but the phone turned itself back on. It didn't matter if the phone was plugged into a charger or not, but they would always do it at some point. My phone even did it so many times, that it rebooted itself! Has anyone else noticed this behavior? I'm wondering if it has something to do with the coverage. VZW coverage seemed different in Detroit compared to Cinci. Voice calls weren't as clear, 3G service was terrible in some areas and horribly slow where coverage was clear. I've used Google Nav here in Cinci a few times and don't remember ever seeing this behavior.
