Until today my ap74 worked fine. Today, it is inop. I can engage the autopilot in all modes through the Dynon Flightdek 180, and when so engaged, the appropriate lights come "on" on the AP74. HOwever, none of the ap74 buttons work (meaning I push them and i cannot engage/disengage a/p, nor set the vert or horizontal mode).
Help please?
