section to mount the GDU 470 unit(s). If upgrading from a GDU 37X to a GDU 470 display, refer to

9.1 Equipment Description
There is no TSO/ETSO applicable to the GDU 470.
Unless a GPS 20A is used for GPS position, a minimum of one GPS antenna is required
for installations using more than one GDU 4XX unit, as the GDU 4XX will “share” the
GPS information with all GDU 470 units. Additional GPS antennas may be used for
redundancy, but are not required.
Make sure that no dust or grit accumulates at the bottom of the display glass. The
GDU 470 display uses invisible infrared beams for touch detection, this makes it very
important to keep the screen clean, especially along the edges.
