Except that the map function is useless to anyone but an ill equipped
daysailor or powerboater.


Ozzy, I'm afraid you're wrong on that one. The small maps are very useful for a
quick reference and quite accurate. Mine shows all navaids, which is a real
help, especially to add another level of comfirmation when tracking a course.
For Suzanne it's been a huge help as she learns to use the charts. Finally the
map feature is just plain fun to use....along with the charts, compass, radar
and our eyes...it's one more level for navigating. I can give coordinates to
Suzanne and she checks our position on the charts, which I then can reaffirm on
the little Garmin's map.
I don't cheap out on such things...or I wouldn't own a boat to begin with.
Beyond that, the GPS 76 mapping was rated as a top pick overall anyway.
