I am trying to help a friend with two older GDU37 screens in his RV10. I am a Dynon man and I am not sure how to go forward. The LH screen has uploaded successfully and is now on V12.60 but the RH screen does not want to read the card no matter what. So the RH one is stuck on V12.0. As is sees itself as a stand alone, after boot up, the EFIS takes up the top half and therefore one can only see a portion of the map. I attach a picture when it was working ok before the upgrade.
