Oscillator Needs Adjustment—The GPS 12 MAP has detected excessive
drift in its internal crystal oscillator which may result in longer acquisition
time. The unit should be taken to an authorized GARMIN service center.
Poor GPS Coverage—The unit cannot acquire the necessary number of
satellites to compute a position. Try another location with a clearer view
of the sky.
Power Down and Re-init—The unit cannot calculate a position due to
abnormal satellite conditions. Turn power off and use other means to
verify the last position shown. Try the unit again later, possibly in a
different location.
