So I was wondering if the GPS can do more as what we can do on a map

Ah yes, the wonderful Garmin manuals - one of their more successful
customer interfaces that they don't even bother to improve. Well done
Garmin!! Another success in dealing with the average joe.

No kidding ... its one of the "useful" kind which describes functions
by how to activate them in the menu (duh) but does not waste time
explaining what exactly it does and how it works .... who would want to
knwo that ?

Well, according to the manual, which I just downloaded, it either does
it through setting Waypoints and creating a Route, or it doesn't do it
that way at all, but by using the "highway" setting.

I can't make heads or tales out of the manual without having a 276c in
front of me to experiment with.

Well ... its too cold to use the boat for a real life test ... I tested
this CDI in simulator mode .... but that only works so well and doesnt
simulate a cross current ...

What it does with NO cross current is, it steers you back to the direct
line from start to target IF you follow the little CDI icon .... hard
to say what it will do with cross current ...

If I had to guess, just a guess, I don't think it will deal with set
and drift in the sense that it will correct a course for you. What it
will do is show you where you are drifting off course, but I don't
think it will automatically create a corresponding plot change or set
up a corresponding course correction (think of it as aiming a rifle
and correcting for a cross wind - inches to the right or left of the
target, etc.) from the git go by entering set and drift.

I will test this in summer and report back ...

My Raymarine RC400 Chartplotter will do it just fine, but then with
Navionics Gold chart, it's over $700.

The garmin unit with map and memory is even more ..
