I recently bought a window mount off ebay for my Inc and have been loving listening to Pandora and using the Navigation program while driving. This weekend I drove a couple of hours back and forth to see a friend and both times I had issues with the amber notification light starting to blink. I had the phone plugged into the Verizon car charger. Could it be that the battery was getting too hot and this was the phones way of notifying me? I live in Florida so it would make sense that the phone was getting rather warm in the window mount. Anybody else have this issue? Can this cause any damage to the phone or the battery? Am I OK as long as I pull the phone down out of the heat whenever I notice this happening?
