THANKS!
Looks like my nuvi350 and my etrex Legend are about 28 meters apart when both are laying on the hood of my suburban.
All things considered thats not too bad. I assume the nuvi uses WGS84 datum or I thought I read that somewhere.

is 'a minute's a mile.' It's not entirely true, especially as you move closer to the poles. But, it's a quick way of estimating distance. So, a degree is ~60 miles, and a second is ~100 feet. (Another inaccuracy of this rule is that it's actually a nautical mile, so statute miles become messier in number). But for quick estimates, it works pretty well.
