I have no idea what units Garmin likes to play with, but I have Lynx NGT-9000. It's a nice unit if you have room for it. It has two tiny screens that you can configure. The screens are sharp, clear and easy to read but they do need to be within line of sight of the pilot.
It talks to Foreflight and WingX on my iPad.
I'm a day vfr pilot and nearly always keep the unit on 1200. The box has a lot of capability and the manual is comprehensive and a bit boring.
If I were going to set my non-RV up for ADS-B again, I'd choose something cheaper.
