GPS 2020 Install ?

Just installed the GPS-2020, selected the GPS 2020 under that menu but it is showing offline. Do I need to configure a serial port also? The transponder also did a firmware update....

Still in hangar, no GPS signal. These photos are after skyview boots up.

TIA

Yeah, the GPS is on a serial port and you have to change it from the GPS 250 to your new GPS 2020:

Thanks Tony !

Once I left the hangar I recalled the serial port switch was needed. Dynon should include that in the onscreen notes
