attempted my first radio change from an old KLX 135a to a Garmin GTR 200 as a second comm. I have a GNS430W and a PMA4000 audio panel.
I think I have something wired incorrectly with the PTT wiring.
-shortly after power up the GTR has a message "Pilot PTT Key Stuck" and will not transmit. I have checked continuity on all the wires Where have I gone wrong I am assuming its super simple.
