The Approach button does not do anything when pressed. The GPS/Nav switches modes without any problems, but the Appr does not do anything. I have used the test button, they all light up. I have to select approach from the autopilot itself, and after selecting it, nothing shows up on the GPS annunciator panel. When I select VLOC, the GPS/Nav will switch to Nav.
