I just downloaded and installed the obstacle database on my GPSmap196. I
love all of the little tee-pee's that are now all over my screen. This is
really neat.

I did the same. Works great. This morning I flew for about three hours and
if I was flying way above the obstructions, the warning would not come up, but
when I was within perhaps 1000 ft vertical and 1 mile horizontal, I'd get the
warning. Since this is a new feature, and not documented in the manual, I
don't know what the real limits are. Anyway, it is definitely worth the $35
upgrade.
