I recently installed a Dynon COM 25 replacing my Garmin SL30 in my RV8. The radio is positioned in the same spot as the Garmin, just below the AFS 5600 EFIS. The Dynon display washes out considerably if you are not looking directly at the display. Obviously I am looking down at about a 30 degree angle and the display becomes very difficult to see. The freq also displays on the AFS EFIS so this is not a major problem, but I'm curious to know if anyone else has experienced this problem, and any recommended solutions.
