Updating gps systems
Some of the Magellan software updates and minor map upgrades can be obtained for free, but most of the map updates must be purchased. Launch Content Manager and log in using your Magellan account information.
If you don't have a Magellan account, visit the main page of the Magellan website, click "Create Account" and follow the directions on the screen to set one up. Right-click the Content Manager icon in the system tray in Windows and the Dock in OS X.
