Introduction
Welcome…
Accessories and Packing List
To obtain accessories for your MX20 please contact
your Garmin dealer.
Help us better support you by completing our on-line
registration form today! Registration ensures that you
will be notified of product updates and new products
and provides lost or stolen unit tracking. Please, have
the serial number of your MX20 handy, connect to
our web site (www.garmin.com) and look for our
Product Registration link on the home page.
The MX20 display lens is coated with a special antireflective coating which is very sensitive to skin oils,
waxes, and abrasive cleaners. It is very important
to clean the lens using an eyeglass cleaner that is
specified as safe for anti-reflective coatings (one suitable product is Wal-Mart Lens Cleaner) and a clean,
lint-free cloth.
Welcome to a new era of aviation navigation. Once again, Garmin has set new standards in features and ease
of use for the general aviation public. The MX20 Multi-Function Display provides a focal point for integrating
many of your navigation needs in an easy to use and convenient package.
The MX20 presents a wealth of information on its six-inch diagonal, 640x480 pixel, color display. The many
features are organized as distinct functions and are designed to closely mimic the traditional instruments used
in the standard cockpit. Each function allows varying degrees of customization. The custom map function is
customizable so you can create a display for almost any configuration you require. The other functions provide
more limited levels of customization so that they retain the look and feel of the instruments they reflect.
The MX20 is capable of creating powerful overlay views where information from a variety of sources can be
presented simultaneously in proper relationship to each other, thus greatly increasing situational awareness for
the pilot.
You can be confident in knowing that you are the owner of the state-of-the-art in aviation and navigation. The
MX20 architecture is designed to support full expansion for both software and hardware enhancements. This
flexibility protects your investment and allows for the ease of adding new features. Our products are built to
last and to allow the flexibility to meet your needs as they change in the future.
About This Manual
This manual may be used as a summary, a reference, and a learning tool. Information is provided about all of
the functions available to the MX20. Your specific installation may not include all of these functions.
Take a few moments to familiarize yourself with the various sections in this manual. The Getting Started section gives an introduction to the controls, basic operation, and organization of the functions in your MX20. Be
sure to read the Getting Started section to learn the rules for using the MX20. The Detailed Operation section
is the reference for each of the functions in the MX20. Refer to the Detailed Operation section when you want
to get into the details on every function and option along with step-by-step instructions.
Not every function is available in all software versions or in every installations.

Introduction
Limitations
The Traffic function is not a collision avoidance system. It is an aid to visual acquisition and does not relieve
the flight crew of their responsibility to “see and avoid.” There are no evasive aircraft maneuvers authorized,
recommended, or provided for as a result of displayed traffic targets. Refer to the traffic sensor documentation
for additional information.
All pilots/operators are reminded that the airborne equipment that displays other ADS-B equipped aircraft
and transponder equipped aircraft via TIS-B is for pilot situational awareness and is not approved as a collision avoidance tool. Any deviation from an air traffic control clearance based on cockpit information must be
approved by the controlling ATC facility prior to commencing the maneuver. Uncoordinated deviations may
place an aircraft in close proximity to other aircraft under ATC control not seen on the airborne equipment and
may possibly result in the issuance of a pilot deviation.
The Terrain function shows you the general terrain elevations relative to your altitude and are advisory in
nature. Individual obstructions may be shown if available in the database. Terrain is displayed from database
information and may therefore contain errors. The Terrain function does not relieve the flight crew of their
responsibility to “see and avoid.” Do not use this information for navigation.
The moving map, weather information, and other displayed information are intended only as aids to situational awareness. The pilot should rely on the appropriate primary means of navigation and consult official
and approved data sources prior to and during each flight.
Refer to your airplane flight manual supplement for more information.

Annunciations
Annunciations
Advisory flags, data flags, and messages appear on the display to give information about the status of the MX20
or to provide operating information.
Advisory Flags
Annunciations will appear on the upper left side of the display to provide advisories for Traffic, Terrain, and
Lightning. Advisory information is monitored and displayed regardless of the selected function. Advisory flags
will flash for approximately 10 seconds when they first appear and then turn solid while they are still valid.
Advisory icons will reduce in size if more than two advisory conditions exist.
Advisory Flags
ADS-B Traffic
The Traffic advisory flag will appear on the left side of the display when traffic is reported to be within ±2000
feet of your altitude and 5 nm of your location. This Traffic advisory is only available when the ADS-B system
with a UAT data link is installed and operational. Refer to the TIS Traffic section for a description of TIS-A and
TIS-B.
Skywatch/TCAD/TIS-A Traffic
The Traffic Advisory/Alert will appear in amber on the left side of the display when the traffic sensor indicates
an alerting condition. Refer to the TIS Traffic section for a description of TIS-A and TIS-B.

Data Flags
Data flags appear on the left side of the display to notify you when there is a loss of reported information.
The data usually displayed, such as lightning or nearby terrain, may still exist, but may not be displayed for
technical reasons. For instance, when the amber TRAF data flag appears it means that the MX20 is not receiving
Traffic information from the sensor. So, traffic may exist in your vicinity, but will not be displayed on the MX20.
All flags are amber unless otherwise indicated.
Data Flag Description

Advisory Hot Key
Advisory Hot Key
The “Advisory Hot Key” feature allows advisory conditions to be quickly viewed with minimal effort by the
pilot. This feature is comprised of three components:
1) An advisory condition is indicated by a white advisory flag on the left side of the screen and the
corresponding Function label will also be highlighted in white when selecting a new Function with
the FN key. This feature allows any Function with a pending advisory to be quickly recognized in the
Function menu.
2) When a function is entered that has an advisory posted, the zoom level will be adjusted to show the
advisory causing object (terrain for example), and the map orientation will be forced to “Track Up 360”
to get a good view of what is around the aircraft.
3) When returning to the previous Function after viewing a Function with an advisory, the original zoom
and map mode will be restored.
This feature is designed to allow the pilot to establish a preferred “cruise” map setup and quickly view an
advisory, then return back to the previous setting. For example:
Normal Cruise Condition
Custom Map Function is being viewed at 5 nm in the ARC mode.
Terrain Advisory occurs at 10 nm in front of aircraft: The Terrain Advisory Indicator flashes then goes steady
on the left side of the display.
Viewing the Advisory
The pilot presses the FN key and sees the TER Function highlighted in white, indicating it has an advisory
condition. Pressing the TER key to enter the Terrain Function at this point will automatically adjust the zoom
level to 10 nm and place the unit in full “360” mode to show overall situational awareness.
Returning To Normal Condition
After evaluating the advisory, to return to normal viewing simply select the original Function that was being
viewed before the advisory was viewed. When this is done, the zoom level will be set back to 5 nm and the
display mode will be returned to ARC mode.
12
Alert Hot Key
Traffic alerts go one step further than the Advisory hot key feature and will automatically bring up the Function Menu showing the Traffic function. This is called the “prompt” mode. A single key press can then be used
to switch the display to the Traffic function. The Alert hot key feature will automatically clear when the traffic
alert condition no longer exists.
Also note that a “pop-up” mode can be enabled on the Traffic function, which makes the Traffic page “pop-up”
when a Traffic Advisory occurs. The “prompt” or “pop-up” mode is selected in the Traffic function.
Options Menu
Most functions have a number of options available. Press the MENU/ENTER key to see the options for the
current function. You change an option by pressing one of the Menu Item keys that are to the right of the displayed option. Many options have more than two choices. Press the same MENU ITEM key repeatedly to view
or select the available choices. Some functions have several pages of options. The lower MENU ITEM key will
allow you to reach the Next Page when multiple pages are available. Press the MENU/ENTER key a second
time to remove the menu from view or wait a few seconds for the options to automatically extinguish.
Thumbnail Feature
The Thumbnail feature provides a small map depiction that is overlaid in the upper left corner of the MX20
display. It provides for enhanced traffic and terrain situational awareness when not specifically viewing traffic
or terrain related functions. For example, both traffic and terrain situational awareness can be maintained
while viewing the Flight Plan Function.
The Thumbnail is shown in both a small and large format, depending on the function currently being viewed.
The Thumbnail is typically presented in the larger format when overlaid on a map. However, on some functions where the Thumbnail would overlay critical information, the smaller format is utilized.
The Thumbnail provides a fixed 5 nm range view of conflicting traffic and terrain. The range depicted by the
Thumbnail is not affected by the current zoom scale set on the main map functions.

Traffic on Thumbnail
TIS, TAS, TCAS, or ADS-B traffic is shown on the Thumbnail in the same symbology used within the Traffic Function. Any traffic within sensor range and 5 nm is shown, in addition to traffic causing an amber Traffic Alert (TA)
traffic. Note that the MX20 supports one traffic sensor in any installation.
Terrain on the Thumbnail
Only “Red” terrain within the 5 nm range is presented on the Thumbnail. This correlates directly to terrain that
is rendered in red on the normal Terrain Function based on the internal terrain database. External TAWS-based
terrain from the Goodrich Landmark is not shown on the Thumbnail.
Obstructions on the Thumbnail
Only “Red” obstructions within the 5 nm range are presented on the Thumbnail. This correlates directly to
obstructions that are rendered in red on the other functions.
Thumbnail Activation
The Thumbnail incorporates logic that will either show or hide the thumbnail from view. It will only be shown
when there is data to be presented and will be removed if not. For example, if there is no “Red” terrain or traffic
within 5 nm, the Thumbnail will be hidden from view. The Thumbnail will not appear on the Traffic Function page if only traffic is presented in the Thumbnail. Correspondingly, it is not shown on the Terrain page if
only terrain is presented in the Thumbnail. This logic eliminates redundant views that would be created by the
Thumbnail and normal views of traffic and terrain. Additionally, the Thumbnail is disabled while operating on
the ground. This state is determined by the “En Route/Ground Transition Speed” set in the System Function
page and is based on GPS ground speed.
Traffic Information Services (TIS)
There are two versions of TIS: TIS-A and TIS-B. Both are described below.
In the TIS-A system, ground radar sensors collect target information. The ground radar sensor then determines
the targets in the vicinity of your aircraft and their bearing relative to your track. Up to eight of the targets are
transmitted by the ground radar sensor the next time it communicates with your TIS-A enabled transponder.
In the TIS-B system, the ground radar sensors collect target information much the same as in the TIS-A system.
However, with TIS-B, all targets collected by the ground radar sensor are broadcast to all aircraft equipped with
UAT data link radios and that are within coverage of UAT ground broadcast stations.
