On my Vista Cx, the basemap shows the whole world if you zoom out far
enough and pan around. I think the European/Atlantic designation is
just the area for which it has roads data. I've not tried it, but I'm
pretty sure you ought still to be able to use it in other parts of the
world, albeit without seeing any roads.
I think your unit was probably just having difficulty getting an initial
fix on the satellites, because California is so far distant from the
last position where it knew where it was. This means it takes a long
time (and it might time out and ask you what to do).
See
http://www.gpsinformation.org/dale/gpsfix.htm for an explanation.
Scroll down to "EZinit Starts" and "Autolocate - Search the sky" for
possible solutions.
I think the description at the above link is a bit out of date so it
doesn't correspond exactly to my Vista Cx. On my unit, you can get into
the appropriate mode by pressing the menu key from the "Acquiring
Satellites" screen. Select "New Location" then "Use Map", then zoom
out, pan to California and press Enter. This should seed the satellite
search so that it proceeds more quickly.
