The setting is digital. The adapter is a genuine apple adapter purchased at best buy $49. Tried 2 different HDMIs the first a basic dynex from bbuy, second an amazon that you reported was working.
VBLUE42, Thanks for all of your work on this forum, as I see you have many posts throughout several topics. I have done a lot of reading here (and at appradio world) trying to find a solution to get this up and running. For what seems like a rather simple setup for whatever reason my appradio2 and 5s never fully communicate with each other and the apps are not accessible (greyed out).
