Netters; I'm definitely no expert on GPS, but from the research that I did on the GPS subject when I was going to purchase one, I learned that the primary difference between Aviation GPS's and Non-Aviation rated GPS's such as Marine units is the times per minute that they update. (I can't remember the URL where I got this info, or I'd post it also, but it was written by a 747 pilot.) The Aviation units update many times more per minute than ground or marine based units. You can test this by taking note of your location (in your car), then turn a corner and head into a new direction and see how long it takes your GPS to update to your new direction / location. Typically you'll notice a lag between the time that you turn, and when the GPS actually updates. Because of the lag time, Marine and ground based units are not recommended for aviation use. The next and maybe more obvious difference is in the databases. Aviation unit databases are far different than a Marine unit. Not to say that you couldn't easily update the database for aviation use, but that's a whole new subject... Maybe the reason Oscar is having difficulties, is because he's switched continents, he may be right on the border of what the satellites can "see". Oscar may need to update his service to change which satellites his GPS is "reading" from.

I think it's good to 99 MPH (clearly posted in the product specs on their website, if you snoop), which is the reason I ended up buying a non-aviation Magellan handheld rather than the equal-priced/equal-featured non-aviation Garmin (the Magellan doesn't hit the wall at 99 MPH).
