We have posted new navigator software to the Software Download Area today. Main Software Version 3.20 for the GPS 175, GNX™ 375, and GNC® 355. This update includes Transponder Board Software Version 2.80 for the GNX 375™.

The following are some of the noteworthy features added with this release:

    NOTE: This feature requires settings to be entered in configuration mode: Setup > Interfaces > Cross-Side Navigator.
  • User waypoint were expanded to support user airports
  • Added support for GPS 175 and GNC 355 to receive ADS-B traffic and weather data from a GNX 375.

Hi: I am buying a Garmin GPS 175
I wonder if this 175 and a Garmin and a Garmin AERA 760 are able to communicate between them?
I already have an AERA760 installed in my RV6A

Answer is yes, I have the 375 (175 plus transponder) and a 760 and use the 760 as a bigger display for the 375. I have the the 375 and 760 connected via bluetooth and RS232 and get ADSB traffic and weather, AHRS, flight plan transfer, and geo located approach charts on the 760. Combo works well.
