Before you can download map detail to a data card or directly to your compatible Garmin GPS, you must "unlock" the CD-ROM. A certificate included with this software allows you to “unlock” the entire CD. Simply follow the instructions on the included certificate. Internet access is required for the unlock process. Next, download data to a data card or to your compatible Garmin unit.
When using a locked MapSource product, the real-time track plotting function of MapSource will work only with GPS products that have valid unlock codes that work with City Select.
