If I use the Garmin GDL-82 kit to upgrade my GTX 327 to ADSB out on my RV7a, would I be able to use the GNS 430w antenna and bypass installing a 2nd antenna (which comes with the GDL-82 kit)? How would this tie in be wired and what software upgrade would be required on the GNS 430? Has anyone done this conversion recently as a do it yourself operation? Thanks..
