In the last year I have had the opportunity to do some extensive travelling and have always taken my GPSr with me from Sweden where I live. It has visited Finland, Denmark, Estonia, UK, Germany, France, Italy, Spain, Luxemburg, Holland, Lichtenstein, Switzerland, Austria, Czech Republic, Poland, South Africa, USA, India, China, Singapore, Japan, S. Korea, Australia, New Zealand, Brazil and yes even Russia! As I didn't know a permit was needed there I didn't inform the authorities. Next time I may leave it at home. Today, it seems that a GPS is not uncommon, in particular as a car mounted attachment.
