8.1 Equipment Description

NOTE
There is no TSO/ETSO applicable to the GDU 46X.
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 46X unit, as the GDU 46X will "share" the
GPS information with all GDU 46X units. Additional GPS antennas may be used for
redundancy, but are not required.
NOTE
Make sure that no dust or grit accumulates at the bottom of the display glass. The GDU
46X display uses invisible infrared beams for touch detection, this makes it very important
to keep the screen clean, especially along the edges.
NOTE
See 34.2.1.5 for information on replacing a GDU 37X display with a GDU 4XX display.
The GDU 46X is not suitable for installation in a type-certificated aircraft.
The GDU 46X is mounted flush to the aircraft instrument panel using four #6 screws. The GDU 46X is
available in two models, GDU 460 and GDU 465. The GDU 460 is a Garmin Display Unit with a GPS
receiver and video input. The GDU 465 provides these same features plus a SiriusXM
