The device does not operate even though the battery is full
After a number of months of satisfactory operation, the device simply does not work anymore. I have reset via the computer a number of times, once with successful use on a round of golf and then no recognition of the course where I am though recognizing courses miles away. Now, always after recharging the battery, the initial :"Please wait" and then a blank screen. I cannot trust the device and need to given the competitions coming up.
