SOFTWARE UPDATES
In addition to databases, the aera 660 will check for software updates when
connected to the internet over Wi-Fi. The aera 660 can use Wi-Fi to update its system
software, as well as any other software available from Garmin.
Software downloads can be either user-initiated or configured to automatically
download as updates become available.
