Bought new safety feature, SPOT sat

I just bought a SPOT system and I'm thinking this could be pretty cool
(especially for trips to central America). It sits on your glareshield
and transmits your position to a sat every 10 minutes. That info is
stored and anyone you choose can go online and see your position on
Google Earth. If you go down they know where your last ping was.
You can also preprogram 3 messages. 1- I'm here and happy. 2- I need
some help 3-911. If you press 3 it goes to the command center and try
try to locate authorities to help find you (in central American it
usually mean finding nearby Americans who will assist). In any case,
this may be the end of the "so and so went down and no one knows where
they are".
