Protecting Your GPSMAP 620
Do not store the GPSMAP 620 where prolonged exposure to
extreme temperatures can occur, because it can cause permanent
damage.
Although a PDA stylus can be used to operate the touchscreen,
never attempt this while operating a vehicle. Never use a hard or
sharp object to operate the touchscreen because damage might
result.
Water Immersion
The unit is waterproof to IEC Standard 60529 IPX7. It can
withstand immersion in 1 meter of water for 30 minutes. Prolonged
submersion can cause damage to the unit. After submersion, be
certain to wipe and air dry the unit before reuse.
Avoiding Theft
To avoid theft, remove the unit and mount from sight when not
in use.
Do not keep your unit in the glove compartment.

Additional Maps
You can purchase additional MapSource map data from Garmin
and load the maps in your GPSMAP 620 internal memory or on an
optional memory card.
To determine the versions of the maps that are loaded on your
GPSMAP 620, open the Menu page. Touch Tools > Settings >
Map > Map Info. Check www.garmin.com/unlock/update.jsp
to see if an update for your map software is available. To enable
additional maps, you need your unit ID (see page 53) and serial
number (located near the power connector).
To load maps or waypoints in your GPSMAP 620 memory or on
your memory card, select the name for your GPSMAP 620 drive
or memory card drive. Refer to the MapSource Help le for more
information.
About GPS Satellite Signals
Your GPSMAP 620 must acquire GPS (Global Positioning System)
satellite signals in order to navigate. If you are indoors, near tall
buildings or trees, or in a parking garage, your GPSMAP 620
may not acquire satellites. Go outside to an area free from tall
obstructions to use your GPSMAP 620.
