MANUAL
Welcome to the easiest-to-use fixed-mount GPS on the water!
The GPS 120XL represents GARMIN’s continuing commitment to provide
mariners with quality navigation information in a versatile, accurate and user-
friendly design which will be useful for years to come. To get the most from
your new GPS unit, it is important that you take the time to read through the
operator’s manual to understand the operating features of the GPS 120XL.
The manual is organized into four sections for your convenience:
Introduction gives a quick overview of the manual and contains the
table of contents and glossary of navigation terms.
Getting Started takes you through step-by-step instructions to initialize
the receiver for first-time use and introduces you to the basic features of the
unit with a quick-start orientation to the GPS 120XL. This section has been
designed to acquaint you with the unit and provide a basic working knowl-
edge necessary to use the unit in typical conditions.
Reference provides detailed explanations of the advanced features and
operations of the GPS 120XL in a topical format. This allows you to concen-
trate on a specific topic quickly, without reading through entire sections of
text that you may not need.
The Appendix section contains installation instructions and items with
multiple listings, such as: map datams, time offsets, and the index.
