The GPSMAP

640 is both a marine and an automotive GPS-
enabled navigation device. When you place the device in a mount
installed on your boat, it powers on in marine mode. When
you place the device in an automotive mount, it powers on in
automotive mode.
This manual is divided in two sections. The rst section describes
how to use the GPSMAP 640 in marine mode, and the second
section describes how to use the device in automotive mode. The
sections are labeled with tabs along the edge of the page to help
identify the usage mode.
