The GIAs contain VHF COM, VHF NAV, and GPS receivers. COM and NAV audio is sent via digital
audio to the GMA 347 Audio Panel. GPS information is sent to the GRS 77 AHRS and both
displays for processing. The GTX 32/33 Mode S Transponder communicates with both GIAs.
Transponder data is sent from the GIAs to the PFD.
