In 2019 Garmin announced the GPS175 (GPS), GNC355 (GPS/COM) and the GNX375 (GPS/XPDR ADS-B in/out). The EASA approval was completed in november 2019. All units feature built in Bluetooth interface (two-way communication with the Garmin Pilot software), WAAS GPS with LPV (localizer performance vertical guidance) approaches. The user interface is very similar to the one found in the big brother Garmin GTN650/Xi series COM/NAV/GPS navigators.
The picture below shows a Cessna 172 that was upgraded with a Garmin GMA345 audiopanel with Bluetooth interface, Garmin GPS175, Garmin GNS430 COM/NAV/GPS, Garmin GTX330 Mode-S transponder. The installation was done in such way that it would be easy to upgrade the GNS430 to WAAS and the GTX330 to a GTX330 w/ES (ADS-B). The installation also includes Garmin G5 Attitude and HSI with GAD13 OAT module. We have prepared the aircraft with wiring for a Garmin GFC500 autopilot. A “RAM” mount was installed in the copilots side to hold a portable device.
