The new Garmin 335 is not much more than a Garmin 330ES, just a little cheaper.
It gets rid of all the wires in my cockpit(floating around) from the portable GPS
bluetooth to the Ipad. Is the 345 much more than that? But, can I file IFR /G with the new Garmin unit. I don't see the relevant TSO's for /G and app certified.
I say NO...please tell me I'm wrong. John
Forget the IFR and /G stuf. These transponders are about making you 2020 compliant for ADS-B. The 330ES will do the job IF you already have a 2020 compliant GPS source - pretty much a 430W, a GTN 650, the bigger units, or the one of the Avidyne navigators. Those are not cheap! The new transponders have those 2020 compliant GPS's built in - that's the big difference - so you don't need an expensive GPS to boot.
Yes, Dynon and Garmin also make hockey puck 202o compliant GPS's, and I am anxious to see if those will play with 330ES's to make a compete "Out" package, and how all the price numbers add up. For guys wanting to install ONE box and make themselves 2020 compliant, these look like units to add to the shopping matrix.
