Which IFR Navigator?
I read the IFR GPS navigator article in the September 2019 Aviation Consumer and think you missed an option: upgrading a Garmin GNS 430 to a GNS 430W, which has WAAS.
At AirVenture I was looking at the new Garmin GPS 175 to replace my old GNS 430. The Garmin rep told me there was a nice rebate available if I traded my GNS 430 for a new GTN-series navigator-something like $4000 toward the GTN. I asked what they were doing with the trade-ins and he said they refurbished them and sold them, but I’m guessing not in the U.S. I asked if that meant that Garmin was continuing to support the GNS 430W and he said absolutely.
