Garmin GPSMAP 230 Owner's Manual page 7

Congratulations on choosing one of the most advanced marine navigation sys-
tems available! The GARMIN GPSMAP 230 combines the proven performance of
GARMIN GPS with powerful G-Chart electronic charting for detailed cartography
and plotting wherever you cruise.
To get the most out of your new navigation system, take the time to go through
this operator' s manual and learn the operating procedures for your unit. This man-
ual is broken down into two sections for your convenience.
Getting Started introduces you to the GPSMAP 230 and provides a tutorial
that will help you become more familiar with the unit. This part will provide you
with a basic working knowledge necessary to use the unit to it's fullest
potential.
The Reference portion is divided into sections that provide detailed instruc-
tions on the advanced features and operations of the GPSMAP 230. This allows
you to concentrate on a specific topic quickly, without reading through entire por-
tions of text that you may not need.
An Appendix section concludes the manual with specific information needed
for custom setup, trouble shooting, and indexing.

WARNING!
The electronic chart is an aid to navigation and is
designed to facilitate the use of authorized govern-
ment charts, not replace them. Only official gov-
ernment charts and notices to mariners contain
all information needed for the safety of naviga-
tion–and, as always, the user is responsible for
their prudent use.
