I believe this was mentioned in another thread but I'd like to see a head unit for the Dynon ADS-B Transponder. Not necessary for Skyview installations but would allow us D100/D180 folks to upgrade. I don't know the typical config but I'd think a head unit that fit in Garmin 327 space would be ideal And assume the transponder itself would interface to the D100/D180 (like the 327) and take input from a GPS for ADS-B (Garmin 5/6/7 series, etc.).
