Stop thinking of the CNX 80 as a moving map GPS but as an FMS. Then keep
the discontinuity in until you have received the ATIS update as to active
approaches and runways. This makes selecting an approach easier as you use
the existing FPL and do not have to extensively modify the current one.

Why is it easier to enter an approach if you leave the discontinuity in?
In either case, you need to hit PROC (possibly having to hit FN first,
if the PROC softkey is not showing), select the approach, select the IAF
(or Vectors), hit EXEC, and then hit ENTER to confirm over-writing the
active flight plan. I hope I got all that right :-)

How does this process change if you leave the discontinuity in or take
it out?
