I don't know if I'm missing something very obvious here, because this worked this afternoon (post-update) but I can't get my datalink symbols to show up on HSD, on autopilot steerpoint it does not steer to the steerpoint (hdg works), and also the HTS/HAD does not pick up radar signals.
I have fully aligned the INS before moving. MDS switch to ON only after the TIME display shows GPS SYSTEM. DLINK page set to ON, Coarse switches to Fine.
Am I missing something ?
