Usefull when we needed it even it would require ergonomics improvements but was usefull

Perhaps this gps is not like Google navigation or garmin, but two times it helps us to find our way when lost in non easy roads. Combined with a classical map, it was a nice help during our trip to costa rica, with an attractive price.
You could improve centralized database with easier search on map or voice for directions.
Good luck for improvements !
