Your Garmin GPS comes with detailed maps that provide directions to almost any destination in the United States, Canada or Mexico. If you plan to travel internationally, Garmin also offers maps for countries in Asia, Europe, Africa and South America. Use Garmin's MapInstall program to install all of the maps you've purchased to your device. The app will only work when you buy a MapSource product from Garmin and Windows Media Player 11 or a higher version is installed on your computer.
