That won't work with the GNS400/500 series.

Direct-To with any type of fix will put a magenta route line on the
map (and potentially other instruments that pull information from the
GPS).

The point, though, was to have the magenta line along the final approach
course, not on the direct path between the present position and the fix.

On the GNS530, you can insert a waypoint into your currently active
flight plan. If you put it after the current fix, it will be inserted
in your current route from your last waypoint. I don't have it in
front of me so I don't recall the exact sequence, but you can put
stuff in and take it out on the fly.

Approaches are different, though, since changing them seems to mutate
them into regular routes. I don't use approaches and the like too
much on the GPS, since it's harder to get it working than to fly it by
hand (or by autopilot).

You can do changes to the IAP flight plan sequence prior to the FAF and
the approach mode will still activate as well as the missed approach.

The limiting factor is an unacceptably large angle of intercept to the
FAF as established by Garmin.

That is not the point. Direct-to on a GNS400/500 will not yield the
unpublished extension of the final approach course unless you happen to
be in the correct position when you activate direct-to. Sure, you will
have a magenta line but it probably won't have a magnetic course of 002,
as per the example IAP.

On the GNS430, Direct-To provides an opportunity to set the course to/from
the waypoint. Press Direct To, enter the waypoint, press Enter, move the
cursor to the course field, set the course, then press Enter again.

I'll take your word for it. That seems more complicated, though, than
using OBS mode.

I just tried that on the 530 trainer and it works the same way. On
relection that might be a better way to go in this hypothetical than
using OBS mode.

Now I remember why I thought OBS was not the best mode. It isn't because it
won't paint the magenta line, because it does; I was off-track on that. It
is because it doesn't autosequence waypoints in OBS mode. Setting the
course in Direct-To does continue autosequencing.
