I completed the remaining Garmin GMA 240 Audio Panel wiring connecting the Grand Rapids Technology (GRT) Electronic Flight Information System (EFIS) and the Engine Information System audio warning inputs. I connected inputs for music and i-Phone through the audio panel (both hard-wired and Bluetooth). Finally, I reinstalled both the Garmin 430W COM/NAV radio and the GMA 240 Audio Panel into their respective panel slots. It’s nice to see the wiring project nearing its end.
