Have used it for years both in the USA. Canada and Western Europe. I use it
with the DeLorme Earthmate Bluetooth system and it functions very well. Only
downside is no voice level guidence. RouteBuddy is more comprehensive, does
voice on the Mac and supports the Garmin and DeLorme GPS   bluetooth connections -
rumored to support direct USB as well. Maps are very pricy compared to Route
66.
