Caring for the GPSMAP 378/478
The GPSMAP 378/478 case is constructed of high quality materials
and does not require user maintenance except cleaning.
Cleaning the Case
Clean the unit’s outer casing (except for the screen) using a cloth
dampened with a mild detergent solution and then wipe dry.
Avoid chemical cleaners and solvents that might damage plastic
components.
Storage
Do not store the GPSMAP 378/478 where prolonged exposure
to temperature extremes might occur (such as in the trunk of a
car) as permanent damage could result. User information, such as
waypoints and routes, is retained in the unit’s memory without the
need for external power. It is always a good practice to back up
important user data by manually recording it or downloading it to a
computer (transferring it to MapSource).
Water Immersion
Cleaning the Screen
The GPSMAP 378/478 screen should be cleaned using a soft, clean,
lint-free cloth. Water, isopropyl alcohol, or eyeglass cleaner can be
used if needed. If these are used, apply the liquid to the cloth and
then gently wipe the screen with the moistened cloth.

Getting Satellite Signals
After you turn on the GPSMAP 378/478, the unit automatically
begins searching for satellites. The GPS Page appears while the unit
is gathering satellite signals and acquiring a x, which should take
only a few minutes. While the GPSMAP 378/478 is getting satellite
signals, the GPS Page shows the status as “Acquiring Satellites.”
As the receiver locks onto satellites, a signal strength bar appears
for each satellite in view, with the appropriate satellite number
underneath each bar. The numbers below each bar represent the
particular satellite that is being received. Numbers above 33 indicate
WAAS satellites.
The sky view shows a bird’s eye view of the position of each
satellite relative to the receiver’s last known position. The outer
circle represents the horizon (north up), the inner circle represents
45º above the horizon, and the center point represents a position
directly overhead. You can also set the sky view to a Track Up
conguration, causing the top of the sky view to align along your
current track heading. Press MENU to change the conguration of
the sky view.

GPS Tips
While the receiver is gathering information, your location on the
map might appear different from where you are actually located.
As soon as the receiver gathers enough satellite information, your
proper location appears on the map.
Any time you have traveled more than 600 miles with the GPS
receiver turned off, the receiver might take longer than normal to
initialize and nd your location.
The GPS receiver can lose satellite signals due to interference from
such items as buildings, tunnels, and heavy tree cover. Monitoring
the GPS status is recommended.
Start/Stop Simulator—starts and stops Simulator Mode, which is
helpful when learning how to use your unit.
To learn about GPS, visit www.garmin.com/aboutGPS/.
Enable/Disable WAAS—enables or disables WAAS capability. See
page 124 of the “Appendix” for more information about WAAS.
Track Up Skyview/North Up Skyview—orients the sky view
display on the GPS Page to North up or Track up.
New Altitude—allows you to manually enter your altitude.
New Location—allows you to enter a new location automatically or
