My 11 year old Garmin eTrex hand-held that I use for biking and hiking is WAAS enabled. I don't typically use it because it uses up the battery faster and I don't need the narrower standard of deviation that WAAS might give.
I can't tell if my less than year old Garmin DriveSmart 61 is WAAS enabled or not. It's not in the specs one way or another. But it doesn't look like most car GPS units have WAAS. I found this interesting article on WAAS and Car units. Why Not WAAS? GPS Review
I recall older automotive Garmins had a setting for "Snap to road" as in it will show you on the closest road even if GPS is calculating that you are off a bit. In most cases this makes sense to assume especially given that the map may not be exactly right either. I don't even see the setting on my newer units.
For someone who may be taking the OB onto dirt trails it's questionable that even if the trail is on the map that the map would be any more accurate than the GPS error. On off-Road, unless you are trying to drive on the edge of a cliff without looking out the window (which would qualify someone for the Darwin Award) WAAS doesn't make any significant difference.
