Havn't used my nav a whole lot. But there have been two times I've used it and the charger quits charging it after about 2 hours. Which, as yuo can imagine kills the battery rather fast. Yesterday it happened and when I pulled the droid off the dash holder it was really hot to the touch. Can this be an overheating issue? gets to hot and it quits charging? I just now noticed that it has a temp guage on the battery minder that I didnt' haave turned on. I"m using the charger that came w/ the dashboard holder.
