NOTE: If a map update is too large for the internal storage of
the device, the software may prompt you to install a microSD
®
card in your device to add storage space (Installing a
Memory Card for Maps and Data, page 24).
The Garmin Express software downloads and installs the
updates onto your device. Map updates are very large, and this
process may take a long time on slower Internet connections.
