4) Ensure that the G5 or any affected LRU is mounted securely. Use the
appropriate tool to check the tightness of all mounting hardware.
5) Look for any heavy objects that may not be fastened tight to the aircraft
structure that could be inducing vibration in the G5's attitude sensors.
6) Look for evidence of water or fluid contamination in the area around the
G5 or any affected LRU.
7) Unplug the connector on the G5 or any affected LRU and check for bent
pins.
8) Inspect the wire harness clamp on the rear of all connectors to verify that
it is not too tight and smashing/shorting the wires. If the wire clamp is
installed upside down, it has sharp edges that can cut into the wires. Verify
the presence of protective wire wrap between the wires and the clamp.
If the condition is not resolved by following the preceding instructions, contact
Garmin Product Support for additional assistance. A Garmin Field Service Engineer
may ask the technician to download the fault logs to a PC and email the logs back
to Garmin to help determine if the condition is caused by a G5 LRU or in the aircraft.

1.8.2 SD CARD SLOT

A stuck or sticking microSD™ card issue can sometimes be caused by the card
thickness variability (especially if there is more than one label on the card). This is
usually caused by the card sticking in the overlay opening, not by the card sticking
to the socket inside the unit. Try another card (without a label if possible) to confirm
the problem before returning. If the second card sticks, the microSD™ socket board
inside the unit may be misaligned with the overlay and the G5 will require repair. If
the thickness of the card was the cause, see if more than one label was on the card. If
the labels weren't the cause, determine what brand of microSD™ card was being used
(Garmin recommends using SanDisk® brand cards).
