5.1 Equipment Description

NOTE
There is no TSO/ETSO applicable to the GDU 37X.
NOTE
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 redundany, but are not required.
The GDU 37X provides a central display and user interface for the G3X system. The display is mounted
flush to the aircraft instrument panel using four #6 captured screws with a 3/32" hex head. The GDU 37X
is available in two models, GDU 370 and GDU 375. The GDU 370 is a Garmin Display Unit with a VFR
WAAS-GPS receiver. The GDU 375 provides these same features plus an XM receiver.
