Getting Started > Charging the GPSMAP 495

Charging the GPSMAP 495

Before using the unit, you need to charge the battery in the GPSMAP 495. 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 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 495 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 495, 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 495 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.

Basic Operation in Aviation Mode > Selecting an Approach

Understanding Vectors

Aviation

The Vectors? option, which appears after you select an approach, determines how you navigate to the ﬁnal approach waypoint.

If you select Yes, the GPSMAP 495 creates an extension of the ﬁnal course beyond the ﬁnal approach waypoint in the database (ﬁnal approach ﬁx [FAF]). On the Active Route Page, a Vector to Final symbol appears beside the ﬁrst approach waypoint.

Active Approach Page

Using vectors in the approach

The GPSMAP 495 provides no guidance to the inbound course. The course deviation needle on the graphic HSI remains off-center until you are established on this ﬁnal approach course. The HSI automatically slews (rotates to show the direction) to the inbound course. The Map Page shows an extension of the ﬁnal approach course using a bold magenta line.

If No is selected for the Vectors? option, the GPSMAP 495 creates a straight-line course directly to the ﬁrst waypoint in the approach (from wherever you are when you initiate the approach). This works much like any other route with course guidance from point to point. A turn is usually required as you cross each waypoint.

CAUTION: Steep Turns are not allowed on an IFR (Instrument

Flight Rules) approach. Follow the approach plate or air trafﬁc control instructions to complete the approach without a steep turn.

If air trafﬁc control clears your approach to an airport, loading the approach cancels your Direct To and initiates a route to the FAF. Load the approach only when cleared by air trafﬁc control.

To cancel the vectors and/or approach:

1. Press Direct To , and press MENU on the Go To Page. OR From the Active Go To (or Active Route) Page, press MENU.

2. Highlight Cancel Approach, and press ENTER to cancel the entire approach. If you enabled Vectors, highlight Cancel Vectors, and press ENTER to navigate directly to the FAF.

The Panel Page shows GPS-derived data in a graphical format, similar to an instrument panel. Keep in mind the differences between this page and your mechanical instruments, as your mechanical panel instruments use sensors that provide information different from that derived using GPS. The Panel Page appears only when the GPSMAP 495 is in Aviation Mode.

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.

Proximity Points

The Proximity Points tab lets you deﬁne an alarm circle around a stored waypoint location. The alarm circle can help you avoid reefs, rocks, or restricted areas. Up to 100 waypoints can be listed with a maximum alarm radius of 99.99 nautical miles, statute miles, or kilometers.

If a proximity alarm circle overlaps an existing alarm circle, a “Proximity Overlaps Another Proximity Waypoint” message appears. Because the unit only alerts for one of the overlap points, use caution when navigating in these areas. If you enter an alarm circle overlap, you are only alerted to the closest proximity waypoint.

Managing Your Tracks

Setting Up and Saving Your Tracks

The GPSMAP 495 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 495 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

Navigate

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.

Record Mode—Wrap records over the oldest tracks when the track log reaches 100%. Fill records a track log until the track log is full (100%). When Off is selected, the unit does not record tracks.

TracBack Tips

When a TracBack has been started, the GPSMAP 495 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:

Always clear the track log at the point that you want to go back

• to (such as a dock or campsite).

The Record Mode option on the Active Track tab must be set to

• Fill or Wrap.

If the track log Interval option on the Active tab is set to the

• Time option, the route may not navigate your exact path (keep the interval set to Resolution for best performance).

•

If the receiver is turned off or satellite coverage is lost during your trip, the TracBack draws a straight line between any point where coverage was lost and where it resumed.

If the changes in distance and direction of your track are too

• complex, 300 waypoints may not mark your path accurately. The receiver then uses the most signiﬁcant points of your track so there are fewer changes in direction.

Marine Mode Pages and Features > DSC

DSC

The DSC Page allows you to control and set up the Digital Selective Calling (DSC) features on the GPSMAP 495.

DSC uses marine VHF radio and GPS technologies to transmit and receive location information. The chartplotter repeats the call properties received from the VHF radio on the chartplotter. The GPSMAP 495 requires input from a DSC enabled VHF radio to show position, and to sound/show alerts from a distress call or position report. Conversely, the VHF radio requires input from a GPS to transmit position coordinates for a distress call or position report. For connection information, refer to “Connecting the Power

and Data Cable” on page 143.

Marine

An emergency DSC distress call allows a vessel in trouble to transmit a substantial amount of information in a single transmission or call, without the need for voice communication. When any nearby rescuer receives the DSC signal, an alarm sounds and they immediately receive the location of the caller. The rescuer can then choose to navigate to the caller’s location to assist, or forward the call on to the Coast Guard. When the Coast Guard receives the call, they can immediately access the caller’s information (such as who they are and the type of vessel) in their database while they are in transit to the caller’s location.

A non-emergency DSC Position Report allows mariners to exchange and show the positions of one another. When a DSC position is received, the mariner can choose to create a waypoint or to show the received location on an electronic map.

Anytime a vessel receives a DSC call, they can store and quickly navigate to that location using a Go To. This makes DSC a time saver, especially in an emergency situation. In order to use DSC, users must ﬁrst register their VHF radio with the FCC and receive a Maritime Mobile Service Identity (MMSI) number.

For more information about Digital Selective Calling and Maritime Mobile Service Identity (MMSI) numbers, refer to page 153.
