So how do I know If I'm getting WAAS or not? Exactly what sattelite numbers are WAAS? I sometimes get a satalite number 53 (I believe). I assume that this is WAAS. However I noitced that when this high number satellite shows up, my accuracy rate does not increase. In fact several times when I shut off the WAAS, my accuracy rate actually INCREASED? I live in Missouri.

I purchased a Mapsource U.S. Topo (version 3.02) CD set some years back. I believe the new ones now are an updated version. Do I have to buy a new set of CD's at the original price to get the update? Thanks, Keith

I have a copy of Mapsource - United States Topo. I purchased it about 5 years ago. Is there an update for this? I went to their website and didn't see anything.

Can someone please explain to me what the practical differences are between these two units? They seem to be priced about the same. Thanks!

I didn't realize there were "screen protectors." Where can I get one?

I currently use a Garmin Legend. It is fine except for in the summer when leaves are on. Garmin advertises that their 76csx gets better reception. Anyone here have practical experiance with this before I buy. They are a bit pricey. Are they really better than the Legend, and by how much?
