When I was doing my transponder update I decide to exit the plane to do something else. At this time I stupidly push with my elbow the on/off button. The update stop at 28% after waiting for a while (nothing happens) I decide to stop everything and to install again everything again. No more transponder of course. I imagine there is no easy solution and I have to send back the transponder to Dynon of finesse Max???
Thank you
