So do I use the FMC to get the runway center line to appear? How do I program ILS information into it? In another aircraft I have, the manual says to use the Radar nav section, though I wouldn't know things like frequency (which it said to put it) because ATC doesn't tell me which runway to use until I'm descending.

Anyways, I'm sure I'm doing something wrong, but I've followed the instructions of online videos, and my LOC hold isn't working. The LOC magenta icon moves to the right and past the center all the way to the right end, and the airplane never turns. The G/S just plain doesn't move.

Thanks again for putting up with my questions and for providing detailed answers.  ;)
