1) Can one use a U.S. purchased GPS unit anywhere in the world; i.e.,
Europe, etc. without a degradation in signal strength?

There are satellites covering most of the world's surface. The GPS
receivers don't differ in what satellites they receive, so they all work
equally well around the world. What might differ is the maps that
pre-loaded, or available, in different units.

This is about as far away from home as my eTrex has been.
