Hello. My name is***** will be your primary care technician.
It would most likely be the antenna yes – or the ground to the vessels common ground. You can do a complete reset, but I would only do this once you've tried everything else because it will erase the personal information on it.
To perform the master reset, please follow these instructions:
With the device powered OFF, press and hold the Quit button
While holding the Quit button, press and hold the Power button
Continue to hold both buttons until the message "Do you really want to erase all user settings?" appears, then release both buttons
Highlight Yes and press the Enter button
The device will now restart. When it fully boots, the device will be set back to factory default settings.
If you have an external antenna on it and suspect that, I would temporarily disconnect it because there is an internal antenna that can at least tell you if the GPS is still working but the antenna is not.
