I have a feeling there may be something else at play here. The GPS
should have a mode similar to "suspend", which would allow you to do
"whatever you want" in the middle of an approach, and then gracefully
come back to it. But approaches aren't supposed to work that way, so
getting the FAA to approve a device that lets the user do stuff he's not
supposed to do in the first place is not likely to happen. (I recall
the flap about the FAA requiring that sferics devices NOT link to the
moving map display).

I don't know anything about the Garmin 480, which I believe Roy was using. But,
with a Garmin 530 I could select OBS mode while IGN was the active waypoint, then
selected a bearing of 062 to have a correct outbound reference. Once I turned
inbound I could select 242 for proper sensing, then as I established track cancel
the OBS mode and the active leg should be correct.
