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 GPSMAP 496 for any purpose requiring precise measurement of direction, distance, location, or topography. This product should not be used to determine ground proximity for aircraft navigation.

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.

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

Caution Elevation

Select the Caution Elevation. If the terrain or an obstacle is within the Caution Elevation you entered, the GPSMAP 496 provides an alert.

Look Ahead Time

The Look Ahead Time for Terrain and Obstacle Alerts determines the time when an alert annunciation occurs. For example, if 120 seconds is selected, the GPSMAP 496 provides an alert up to 120 seconds before you reach the terrain or obstacle.

Alert Sensitivity

The three Alert Sensitivity settings (Terrain, Obstacle, and Descent Rate) determines what level of alerts are annunciated. The

GPSMAP 496 defaults to High sensitivity, which annunciates all red and yellow alerts at the time set in Look Ahead Time. Medium sensitivity annunciates all of the red and the highest priority of yellow alerts, and Low only annunciates red alerts.

The graphic HSI depicts the course to the destination or the next waypoint in a route, current ground track, off course error, and a To/From indication. The rotating compass indicates your current ground track at the top of the page.

The course pointer and course deviation needle indicate the course and whether you are on the course. A bug indicator provides information to guide you back to the course if you stray off course.

If you move off course, the Course Deviation Indicator, or needle, indicates how far off course you are, left or right, based on its placement along the course deviation scale. To get back on course and center the needle, steer toward the needle.

The course deviation scale setting is adjustable for Auto, ±0.25, 1.25 or 5.0 (nautical mile, statute mile, or kilometer) full-scale deﬂection. The course deviation scale appears on the lower right corner of the HSI. The default setting is Auto, which uses three factors to determine the distance from the center of the CDI to full left or right limits:

• When you are within 30 nm of any airport in the active route, Auto sets the CDI scale at 1.25.

• When you are on an approach leg or within 2 nm of the FAF or MAP waypoints, Auto sets the scale at 0.25.

• If the previous two conditions do not exist, Auto sets to 5.0.

Calculating the Weight & Balance

Weight & Balance may be used during your pre-ﬂight preparations to verify the weight and balance conditions for your aircraft. By entering the weight and arm values on this page, the GPSMAP 496 can calculate the total weight, moment, and center of gravity (CG) to ensure a safe ﬂight.

Before entering the various ﬁgures, you need to determine the empty weight of the airplane and the arm (or “station”) for each weight entered. These ﬁgures should be determined using the pilot’s operating handbook for your airplane, which also notes the weight limitations and fore/aft CG limits. Compare those ﬁgures to the values calculated by the GPSMAP 496.

To perform weight and balance calculations:

Managing Your Tracks

The GPSMAP 496 draws an electronic breadcrumb trail or “track log” on the Map Page as you travel. The track log contains points along its path, including time, and location for each point.

The track log starts recording as soon as the GPSMAP 496 gets a location ﬁx. For the best results, clear the track log before you start traveling because when the track log is full, new track points overwrite the oldest track points.

The percentage of memory used by the current track log appears at the top of the Active sub tab. After the track log is cleared, it shows zero percent. When the screen reaches 100%, the most recent track points start to overwrite the least recent track points (if Wrap is selected for Record Mode). To avoid losing track points, save the track log when it approaches the 99% mark.

You must ﬁrst save the track log before you can use the Track feature. The Save feature allows you to store up to 15 track logs from certain times and dates.

To access the Track tab:

1. Press Menu twice to open the Main Menu.

2. Highlight Track from the vertical list of tabs.

Navigating a Saved Track

The TracBack function allows you to retrace your path using the track log automatically stored in the receiver’s memory, which eliminates the need to store waypoints along the way. TracBack routes are created by reducing your track log into a route with up to 300 turns and activating an inverted route along those points. When

TracBack Tips

When a TracBack has been started, the GPSMAP 496 divides the track into segments called legs. Up to 300 temporary turns are created to mark the most signiﬁcant features of the track in order to duplicate your exact path as closely as possible. To get the most out of the TracBack feature, remember these tips:
