There is no TSO/ETSO applicable to the GDU 37X.
NOTE
Unless a GPS 20A is used for GPS position, a minimum of one GPS antenna is required
for installations using more than one GDU 37X unit, as the GDU 37X will "share" the
GPS information with all GDU 37X units. Additional GPS antennas may be used for
redundancy, but are not required.
The GDU 37X provides a central display and user interface for the G3X system. The display is mounted

is available in two models, GDU 370 and GDU 375. The GDU 370 is a Garmin Display Unit with a VFR
