INTRODUCTION > CAUTION
Caution
Failure to avoid the following potentially hazardous situations may
result in injury or property damage.
The GPSMAP 496 is designed to provide you with route suggestions. It
does not reflect road closures or road conditions, traffic congestion, weather
conditions, or other factors that may affect safety or timing while driving.
Use the GPSMAP 496 only as a navigational aid. Do not attempt to use the

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 shown to the consumer.
Virtually all data sources contain inaccurate or incomplete data to some extent. This is particularly true outside the United States, where complete and accurate
digital data is either not available or prohibitively expensive.
TFR Data: Temporary Flight Restriction (TFR) data is provided by the FAA and may not be updated outside of normal business hours. Confirm data currency
though alternate sources and contact your local FSS for interpretation of TFR data.
vi GPSMAP 496 Owner’s Manual
The Global Positioning System (GPS) is operated by the United States
government, which is solely responsible for its accuracy and maintenance.
The government’s system is subject to changes which could affect
the accuracy and performance of all GPS equipment, including the
GPSMAP 496. Although the GPSMAP 496 is a precision navigation device,
any navigation device can be misused or misinterpreted and, therefore,
become unsafe.

GETTING STARTED > CHARGING THE GPSMAP 496
Charging the GPSMAP 496
Before using the unit, you need to charge the battery in the
GPSMAP 496. Plug the unit into a 12 Volt 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 12 Volt adapter into a cigarette lighter receptacle if
you have a cigarette lighter adapter. Use care when routing
the adapter 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 STARTED > GETTING SATELLITE SIGNALS
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 fix. 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 WAAS 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 configuration,
causing the top of the sky view to align along your current track
heading.

A power source indicator shows the unit is operating off
power ( ), that the unit is charging ( ), or that an

Receiver Status
The progress of satellite acquisition is shown in three stages:
• No signal strength bars—the receiver is looking for the
satellites indicated.
• White signal strength bars—the receiver has found the
satellite and is collecting data.
• Green signal strength bars—the receiver has collected the
necessary data from this satellite.
As soon as the GPSMAP 496 has collected the necessary data from
the best satellites in view to calculate a fix, the status field indicates
the status of the receiver. The unit then updates the location, date,
and time.
The Receiver Status field shows one of the following conditions:
• Searching the Sky—the receiver is looking for satellites.
• AutoLocate—the receiver is looking for any satellite whose
almanac has been collected, which can take up to 5 minutes.
• Acquiring Satellites—the receiver is looking for and collecting
data from satellites visible at its last known or initialized location,
but has not acquired a fix.
• 2D GPS Location—At least three satellites have been acquired
and a two-dimensional location fix has been calculated. “2D
Differential” appears when you are receiving DGPS corrections in
2D mode and a “D” appears on the strength bar of satellites being
corrected.
• 3D GPS Location—At least four satellites have been acquired
and a three-dimensional fix has been calculated. “3D Differential”
appears when you are receiving DGPS corrections in 3D mode and
a “D” appears on the strength bar of satellites being corrected.
• Lost Satellite Reception—the receiver is no longer tracking
enough satellites for a 2D or 3D fix.
• Receiver Not Usable—the receiver is unusable, possibly due to
interference or abnormal satellite conditions. Turn the unit off and
back on to reset.
• Simulating GPS—the receiver is in Simulator Mode.
• GPS Off—the GPS receiver is turned off.

GPS Tips
While the receiver is gathering information, your location on the
map can show as different from where you actually are located. Be
patient; as soon as the receiver gathers enough satellite information,
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
initialize and find your location.
The GPS receiver can lose satellite signals due to interference from
such items as buildings, tunnels, and heavy tree cover. Monitoring
