Andy A Posted November 1, 2018 Report Share Posted November 1, 2018 I just upgraded my Dynon SV GPS 250 to the new SV GPS 2020 ADSB compliant model. I have Dynon Skyview Classics with the Dynon 261 Transponder and 470 ADSB unit. The old 250 was working perfectly for weather and ADSB in. After I installed the 2020, everything is working exactly the same as before. It’s picking up other planes but not sending an out signal. Does anybody have any recommendations on what could be wrong?

Brian Posted November 1, 2018 Report Share Posted November 1, 2018 There is a setting that needs to be changed on the Skyview to use the 2020. It's listed in the installation manual. Link to comment Share on other sites More sharing options...
Andy A Posted November 4, 2018 Author Report Share Posted November 4, 2018 I spoke with Dynon’s tech support and got it worked out. The firmware was not up to date on the transponder. If anyone else has this problem go to the transponder setup screen. The first line is the transponder firmware version. Look at the last few numbers. The current version is .11. If yours isn’t up of date look for the load button at the bottom of the screen and press it. The firmware is already saved in the unit but hasn’t been installed until you load it. Easy fix.
