The only thing we couldn't figure out an easy thing for is how to
back it up to the holding pattern if you let it sequence out of
it while circling an additional time. You can turn the FPL back
to the holding entry (but not the hold) where it thinks you
want to go direct to the fix and hold again. We just ignore
the GPS proposed nav instead and fly around one more time and
let it catch up with us when we finally go inbound.

Hit -D-, scroll up or down to the holding fix, then select Hold from the
menu (might have to hit More once or twice to get to the right page).
Watch out for how it describes holds: the GPS *always* uses "course to" to
describe the inbound leg. If the fix is a VOR, ATC will have probably said
"on the XXX radial", which is essentially "course from".

My experience is that most people never really learn most of the -D-
functions. They get "Direct" and "Dest", but rarely explore the OBS, CRS
To, CRS From, Hold, etc.

I once actually found a use for the Parallel Track stuff. Coming back to
HPN, ATC gave me "Direct Tappan Zee Bridge". The bridge isn't in the
database, but I was heading south and I know the bridge is about 5 miles
west of the airport, so I just put in "direct HPN" and selected a parallel
track offset 5 miles to the right :-)
