First some background. I'm working on getting my operating conditions changed to remove the "VFR Only" wording (Canada) so I can do IFR in my newly equipped RV-9A. The TC inspector has been really good, but has expressed concern that my AVMAP EFIS Ultra isn't a backup for the CDI/VDI on my GPS 175 (in case I lose my single HDX display), and also that my AVMAP and my MGL Razor control head are too far apart (attitude/airspeed/altimeter and LOC/GS) to be usable for backup. They are looking for a 30 degree field of view.
So, I'm looking into replacing my AVMAP EFIS Ultra with a Garmin G5. The only way that will satisfy both the concerns listed above is if I can send both my Nav LOC/GS (SL30 via RS232) and GPS 175 (via GAD 29 ARINC) to a single G5. The diagrams in the G5 manual shows that both items connect to the sole RS232 RX pin on the G5. Since the SL30 uses only RS232, can the GPS 175 connect with just a copy (splice, with Dynon ARINC) of the ARINC 429 OUT? I don't need to send anything from the G5 back to the GPS, so maybe I can skip the ARINC IN.
Any idea if this is possible? I'm open to other product suggestions too.
