Actually, I don't even understand how that can be, I thought they were accurate to around 30ft? or is it 30m (90ft). Do you think you lost signal in canyons or something like that? Or maybe it just seemed like 500ft?

First, thanks every one for all the info!
As for GPS accuracy, I think that a modern GPS itself would be very accurate. Most receivers will pick up at least 12 signals giving you a very accurate read on where you are. There shouldn't be any problems with lost signals as most populated areas around the globe have very good satellite coverage which is why you guys have accurate indicated ground speed (unless you're speeding along under a triple canopy jungle). In my former life, I used to hang out the side of a helicopter, I wore a Suunto GPS on my wrist and it gave me very accurate indicated speed but it was a very basic GPS receiver. My point is, if there were any "lag" in information, then it would seem to me that this lag would be the fault of the software interface, not the GPS itself. With that said, is this an isolated incident that one 550 has this lag? Would a firmware upgrade fix it? So far, it sounds like the 550 is the way to go.
Thanks again,
Keith
