Using Additional Map Data
The GPSMAP 2106/2110 comes standard with a built-in basemap showing cities, interstates, coastline detail, and U.S. Tide stations. Optional preprogrammed Garmin data cards and MapSource CD-ROMs enhance the versatility of your GPSMAP 2106/2110. With optional BlueChart cartography, you can access marine navaids, wrecks, obstructions, anchorage locations, shaded depth contours, intertidal zones, spot soundings, port plans, and more. The GPSMAP 2106/2110 supports Garmins new BlueChart g2 technology. This cartography features integrated mapping, 2-D or 3-D map perspective, tide and current data, improved IALA symbols, navaids, marinas, boat ramps, roads, and more. You can also access additional data including highly detailed coastal roads and points of interest such as restaurants, lodging, and local attractions. Full-color aerial photographs of ports, marinas, bridges, and navigational landmarks are also included on many preprogrammed BlueChart g2 data cards. See your Garmin dealer or visit the Garmin Web site (www.garmin.com) for more information on available preprogrammed Garmin data cards and other MapSource programs.

BASIC OPERATION > FINDING AN ITEM

Finding an Item

Press FIND to search for items including waypoints, cities, geographic points, celestial information, tides, and currents. If you pan around on the map window and press FIND, the unit centers its search from the map pointer location. When using BlueChart, BlueChart g2, or MapSource data, your location or the map pointer must be within the map outline area to search for information from that area. To nd an item from your current location:
1. From any page, press FIND to open the Find From Current Position Page.
4. Some items have a Filter List button that allows you to enter letters or numbers of the item name. The search result shows only items matching the entered letters or numbers. Highlight the Filter List button, and press ENTER. Enter data, as needed, to narrow your search.
To nd an item from another location on the map:
1. Open the Map Page. Use the ROCKER to pan to the location you want, and then press FIND. The Find From (Location) Page appears. 2. Using the ROCKER, highlight a category, and press ENTER.
To view details about an item:
Highlight an item in the search results list, and press ENTER. The Review Page appears, showing item information, map location, chart name, distance/bearing, and options for creating a waypoint or viewing the next item in the search results list.

BASIC OPERATION > CREATING AND USING WAYPOINTS
Creating and Using Waypoints
The GPSMAP 2106/2110 stores up to 4,000 alphanumeric waypoints, each with a user-dened icon, comment, depth, and water temperature.
NOTE: If you are using a Garmin GSD 21 or GSD 22 sounder module, the Depth and Water Temp elds ll in automatically.
You can create waypoints using three basic methods: ENTER/MARKuse the ENTER/MARK key to quickly mark your current location. Graphicallyuse the map display to dene a new waypoint location. Manuallyenter new waypoint coordinates manually. Use the ENTER/MARK key to capture your current location (or pointer or map item location) to create a new waypoint. You must have a valid position x to mark your current location.

Datums are used to describe geographic locations for surveying, mapping, and navigation and are not actual maps built in the unit. Although more than 100 datums are available, you should change the datum only if you are using a map or chart that species a different datum.
WARNING: Selecting the wrong map datum can result in substantial position errors. When in doubt, use the default WGS 84 datum for best overall performance.

You must be using a Garmin weather product for this data to appear. Headingset the reference used in calculating heading information. You can select Auto Mag Var, True, Grid, and User Mag Var. Auto Mag Var provides magnetic north heading references that are automatically determined from your present location. True provides headings based on a true north reference. Grid provides headings based on a grid north reference. User Mag Var allows you to specify the magnetic variation at
your present location and provides magnetic north heading references based on the variation you enter.
WARNING: If you select User Mag Var, you must periodically update the magnetic variation as your location changes. When using this setting, the GPSMAP 2106/2110 unit does not automatically calculate and update the magnetic variation at your present location. Failure to update this setting can result in substantial differences between the information displayed on your unit and external references, such as a magnetic compass. 1.

You can set the sonar display to show a split screen view of a zoomed portion of the sonar, split frequencies, bottom lock (display scaled from the bottom up) or a combination of these options. For example, you can choose to show dual frequency at a 2X zoom (Dual 2X) on one half and normal range dual frequency (Dual) returns on the other half. The display mode appears at the bottom of each sonar display.
The sonar function window contains a right-to-left moving sonar image of the water beneath your boat. Items appear as they pass under the transducer. The most recent data is shown on the right side of the screen. The right side of the screen contains a scale reecting the depth of the area being shown. The top-left corner shows the depth, water temperature, and speed through water (if equipped with a temperature or speed sensor).

APPENDIX > INSTALLING AND REMOVING DATA CARDS
The GPSMAP 2106/2110 uses optional Garmin BlueChart and MapSource data cards. You can use optional preprogrammed BlueChart g2 data cards. Insert data cards in the card slots located on the left side of the unit. You can install or remove data cards at any time, whether the unit is on or off. To install a data card:

LORAN TD Feature

How Can Garmin Help You with DSC?
To receive Distress Calls or Position Reports, you must have a DSC-equipped chartplotter as well as a VHF radio with DSC support. During normal, nonemergency Position Report communication, Channel 70 (156.525 MHz) has been set aside as the VHF/DSC digital call channel. For a Distress Call, a mariner presses the MayDay button on the VHF radio. The call transmits on an emergency channel with the MMSI number attached to the call (if you have DSC support). Any DSC-equipped mariner (on sea or land) within range can receive the call.
The LORAN TD (Time Delay) feature eases the transition from using LORAN to using GPS. The GPSMAP unit automatically converts GPS coordinates to LORAN TD for those who have a collection of LORAN xes for favorite shing spots and other waypoints recorded as TDs. You can show your position as a TD or enter waypoints as TDs. The expected accuracy from this conversion is approximately 30 meters. When the unit is placed in the LORAN TD format mode, it simulates the operation of a LORAN receiver. Position coordinates can be displayed as TDs, and you can use all navigation functions as if the unit was actually receiving LORAN signals.
Using the LORAN TD Format
When creating new waypoints using LORAN TD coordinates, you must set the correct LORAN chain number and secondary stations in the Setup TD eld before storing a waypoint. You must have the correct chain number and the secondary station identiers to use this option correctly. These values vary for each coordinate set or geographical location. Failure to enter correct information could result in inaccuracies for the desired destination. After the waypoint is stored in the units memory, it always references the LORAN chain number and secondary stations currently selected in the Setup TD eld. If you enter a different LORAN chain number, change the secondary stations or offsets in the Setup TD eld, the active waypoint information reects those changes. Because
APPENDIX > CARING FOR THE GPSMAP 2106/2110
the GPSMAP 2106/2110 unit does not rely on the LORAN signal for navigation, it can reference a different GRI chain or secondary stations and still navigate to the location stored in memory. The LORAN Position Format eld is located on the Units sub tab on the Main MenuSystem tab. The Loran TD Setup window contains the elds to select the LORAN Chain Number, Primary and Secondary Stations, and TD Offsets.
