I don't recall how much internal memory the unit comes with, but by the time I had downloaded my 2nd or 3rd map update it was overwhelmed and I had to buy a 4gb microSD card to expand the memory. If you need to do this, don't buy the overpriced Garmin memory from their website, buy one from amazon.

It is a GPS and should be usable ANYWHERE in the world. However will you be able to get map data for it,????? You will have to ask the manufacturer that one but the satellites don't discriminate over national boundaries.

No, and a big drawback as well is that though you can add waypoints (like favorite places or intersections) to routes and download waypoints from your computer, you cannot download routes either from sources like Google or from any route software sold for/by Garmin.
