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.
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.
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.
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.
Charge Mode
NOTE: While in Charge Mode, the unit draws a small amount
of current from the aircraft/vehicle/boat battery. To avoid
discharging the vehicle’s battery, disconnect the external power
cable from the GPSMAP 496 when not in use for several days.
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.
GPS Page
NOTE: While acquiring satellites, the Map Page can show the
wrong location, such as China. This does not mean your unit
has the wrong data loaded. The GPS receiver needs a few more
minutes to acquire satellites and nd your current location.
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 conguration,
causing the top of the sky view to align along your current track
heading.
A power source indicator shows the unit is operating off battery
power ( ), that the unit is charging ( ), or that an
external power source is in use ( ).

The progress of satellite acquisition is shown in three stages:
No signal strength bar—the receiver is looking for the
satellites indicated.
White signal strength bar—the receiver has found the
satellite and is collecting data.
Green signal strength bar—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 x, the status eld indicates
the status of the receiver. The unit then updates the location, date,
and time.
Receiver Status
The Receiver Status eld 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 x.
2D GPS Location—At least three satellites have been
acquired and a two-dimensional location x 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 x 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 x.
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 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.
To learn about GPS, refer to “Learning about GPS” on page 139.

The GPSMAP 496 contains a Simulator Mode. Simulator Mode
is helpful for practicing with the unit indoors or when no satellite
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
