Hi,My name is***** will try my best to help you with your question.
If the device will not start up correctly after attempting to update the firmware, then the firmware on the device has likely gotten corrupted.
You can try updating again, however if that doesn't work then the device will need to be returned to Garmin for repair.
Hi, just checking in on your question, do you need any further assistance?
Given the age of the device, the best course of action would be to replace it.
