Montana 680t charging issue
as a long time user of garmin gps devices I noticed from the very beginning that my Montana acts strange during charging. In addition, the device suddenly stopped to work yesterday on a terrain, however just few minutes before this the indicator showed 45% of battery. next, after charging it over the night with wall charger, the device stopped to be charged at 92%. there is blinking symbol for charging for some seconds and then the symbol disappears for some seconds, and so on. I received a device two weeks ago as a gift. I also noticed that when i use computer and usb cable, there is no battery indicator on the display of my Montana 680t. I have impression that this issue is not a common one, so I assume something is just wrong with my battery? I used the device with three AA batteries for very short time and all was fine. someone? Thanks.
