approved Maintenance or Installation Manual instructions.
9.1 GDU 37X
9.1.1 SD Card Slot
A stuck or sticking SD 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 SD socket board inside
the unit may be misaligned with the overlay and the GDU 37X 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 SD card was being used (Garmin recommends using SanDisk® or Toshiba brand cards).
9.1.2 Crosstalk Error (Dual or Three Screen Systems)
Crosstalk Error messages occur if there is a mismatch in GDU 37X software versions. If this occurs, the
GDU’s will not communicate with each other, and a software mismatch message will be reported on the
INFO page (press the MSG softkey). Ensure both displays are running the same software version to clear
the issue.
