Important Information
MAP DATA INFORMATION: One of the goals of Garmin is to provide
customers with the most complete and accurate cartography that is
available to us at a reasonable cost. We use a combination of governmental
and private data sources, which we identify in product literature and
copyright messages displayed to the consumer. Virtually all data sources
contain some inaccurate or incomplete data. In some countries, complete
and accurate map information is either not available or is prohibitively
expensive.
TFR Data: Temporary Flight Restriction (TFR) data is provided by the
FAA and may not be updated outside of normal business hours. Conrm
data currency though alternate sources and contact your local FSS for
interpretation of TFR data.

Care Information
Contact Garmin if you have any questions while using your
GPSMAP 396. In the USA contact Garmin Product Support by
phone: (913) 397-8200 or (800) 800-1020, Monday–Friday,
8 AM–5 PM Central Time; or go to www.garmin.com/support.
In Europe, contact Garmin (Europe) Ltd. at +44 (0) 870.8501241
(outside the UK) or 0808 2380000 (within the UK).
Cleaning the Unit
The GPSMAP 496 is constructed of high quality materials and does
not require user maintenance other than cleaning. Clean the unit
using a cloth dampened with a mild detergent solution and then wipe
dry. Avoid chemical cleaners and solvents that may damage plastic
components.
Storing the GPSMAP 496
Do not store the GPSMAP 496 where prolonged exposure to
temperature extremes can occur (such as in the trunk of a car) as
permanent damage may 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 PC
(transferring it to MapSource).
Immersing the Unit in Water
The GPSMAP 496 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 or charging.

Charging the GPSMAP 496
Before using the unit, you need to charge the battery in the
GPSMAP 496. Plug the unit into a vehicle power connector to
charge. You can use the unit while it is charging.
If you do not want to use the unit, but you would like to charge the
battery, you can put the unit into Charge Mode. Connect the unit to
an external power supply. Press and hold the POWER key. Instead
of completely turning off, the unit now goes into Charge Mode, as
shown below.
To charge the unit’s battery:
1. Lift the rubber weather cap to expose the power connector
on the back of the unit. Refer to the image on page 1 for
connector location.
2. Align the notches, and push the plug into the connector until
fully seated.
3. Plug the vehicle power cable into a vehicle power outlet
(cigarette lighter receptacle) if you have a vehicle power
cable. Use care when routing the power cable; be certain that
it does not interfere with vehicle operation.
The unit begins charging as soon as external power is applied.
NOTE: While in Charge Mode, the unit draws a small amount
Placing the unit in Charge Mode charges the unit more quickly than
when the unit is turned on and reduces draw on the aircraft/vehicle/
boat battery.
Information about Charge Mode
Applying external power to the GPSMAP 496 automatically turns
on the unit for full operation. If the battery is present and needs to be
charged, the external power source charges the battery while the unit
is in use.
After using the unit a lot, you may notice that the lithium-ion battery
in the unit is not holding a charge any more. This is common for
lithium-ion batteries. Contact Garmin or your Garmin Dealer to
order a Battery Pack replacement if you are experiencing charging
issues with your battery.

Getting Satellite Signals
After you turn on the GPSMAP 496, the unit automatically begins
searching for satellites. The GPS Page appears while the unit is
gathering satellite signals and acquiring a x. This process should
take only a few minutes. While the GPSMAP 496 is getting satellite
signals, the GPS Page shows the status as “Acquiring Satellites.”
It can take a few minutes to acquire satellites and show your current
location on the map. Be patient as the unit acquires satellite data.
To get signals more quickly, be sure the antenna is raised to the up
position shown in the image on page 1.
Viewing GPS Status With the GPS Tab
The GPS tab provides a visual reference of satellite acquisition,
receiver status, and accuracy. The sky view and signal strength bars
give an indication of what satellites are visible to the receiver and
whether they are being tracked.
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 shown below each bar represent
the particular satellite that is being received. Numbers above 33
indicate EGNOS satellites.
The sky view shows a birds-eye view of the location of each satellite
relative to the receiver’s last known location. The outer circle
represents the horizon (north up), the inner circle represents 45º
above the horizon, and the center point represents a location 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.

While the receiver is gathering information, your location on the
map can show as different from where you actually are located. Be

your proper location is shown on the map.
Any time you have traveled more than 600 miles with the GPS
receiver turned off, the receiver can take longer than normal to

signals are available or if the antenna is not connected. All
waypoints and routes created in Simulator Mode are retained in
memory for future use. The following section describes how to use
Simulator Mode and walks you through some basic navigation using
the simulator.
NOTE: Do not attempt to navigate using Simulator Mode. When
the unit is set to Simulator Mode, the GPS receiver is turned off.
Any Satellite Signal Strength Bars shown are only simulations
and do not represent the strength of actual satellite signals.

avIatIon
CAUTION: The approaches provided in the Jeppesen database
are for monitoring purposes only. The GPSMAP 496 is not an
IFR-approved instrument and should not be used as a primary
source of navigation guidance in instrument conditions.
When you select an approach, it replaces the destination airport with
the sequence of waypoints for the selected approach. Keep in mind
that the airport must have a published approach (GPS, RNAV, VOR,
NDB, localizer, or ILS) and only the nal course segment (usually
from nal approach x to missed approach point) of the published
approach is available in the GPSMAP 496.
NOTE: When using a route, the selected approach for the
destination airport overrides your current route. The original
route is saved in the Route tab.
You can select an approach several ways:
Press Direct To and press MENU on the Go To Page, as
•
described in the steps to the right.
