I'm finding everything else I need (Alt hold, V/S, Speed Hold, etc) except probably the most critical of all...the LNAV. I have looked everywhere and can't find an LNAV button. I'm not even sure how to put this thing in managed mode either. Push up on the heading knob doesn't seem to turn on the managed mode like it does in the a320, even after setting a pre-flight from the map before starting the sim.
