Here is what we are doing. Amazing the avionics sales guys don't know this stuff. But my question is if we do the gtx45r I need a GPS antenna (GA35) and a WAAS receiver (GPS20A) to feed the GTX45r correct?

Do I need a gps receiver/antenna for the G3X also?

G3X Touch 10" landscape
Guardian 9.7" Ipad air 2 mount
GTR20 Remote comm
Vertical power sport
GEA 24 EIS
GTX45R
GA35 WASSGPS antenna
GPS20A
(We are doing all remote mount to try and keep the CG back with the added weight of a turbo and intercooler and upgraded alternator)

Obviously there is a bunch more connectors and install kits and senors, I just outlined the major components.
From my limited understanding you definitely need gps20a to feed 45r. And also a gps antenna of some type (I believe there’s multiple you can choose from). I find it amazing even garmin tech contridicts themselves on these topics.
