What Is the Purpose of the SD Card in a navigation?

Hand-held or car-mounted GPS devices can save you a world of inconvenience when you're traveling or driving through an unfamiliar location. A full-featured GPS can guide you through tricky freeway interchanges, warn you of changes to the speed limit and direct you to the nearest roadside diner or restroom; however, this data changes constantly,you need to keep your device up-to-date by purchasing them on a navigation SD card.

A GPS map card is a standard SD card preloaded with map data or other pertinent information for your GPS. Using a memory card with your GPS unit can take your navigation to another level, enabling you to update existing maps, add maps or add multimedia files. GPS memory card slots typically accept removable micro, mini or full-size Secure Digital cards. You can purchase these tiny cards with maps on them.
