Thought it might be nice on my next cruise if I had a GPS thingy for my

can get one for the Caribbean that you can use w/o needing to be
connected to Internet or cell phone tower?

Motion-GPS is one you can get. You will have to download the maps while
connected to the Internet. After that you don't have to be connected.

thanks


Don't necessarily count on the GPS antenna working though. On Charles'
ATT iPHone 4, he was able to get a location while in the Bahamas. On my
Verizon iPhone 4 I couldn't at the same location on the ship. When I
went to the Apple Store about the issue later, they said there is no way
to check was was going on. They just gave me a new phone but said don't
count on it working either. The Verizon and ATT phones are different
inside, so that could have been the issue. Or maybe his was getting
enough cell signals from islands so it could triangulate. And it's not
like there weren't GPS satellites in range in the sky. My Garmin hand
held showed a sky full of satellites. And my hand held Garmin caught a
signal in less than 60 seconds while Charles' iPhone took much longer.
And mine didn't catch at all.

So don't count on it.

And also understand that even if you do get the GPS to connect, you
won't be able to get maps via internet connection. So you will have to
preload and save the maps for the idea to work (if you do catch satellites).

But to be honest, the best option is a small hand held Garmin.
