Custom Map
obstructions
Obstructions, such as towers and other man-made
objects, are part of the GMX 200 updateable database.
Obstructions over 250 feet high are shown on the maps
with tower symbols. The symbol is color coded to sig-
nify the relative altitude of the tower to your aircraft’s
altitude and follows the same conventions as the color
coding for terrain.
Obstruction icons
Objects that are within 100 feet of your altitude are
shown in red; objects that are within 1000 feet of your
altitude are shown in yellow; objects with towers that
are more than 1000 feet below your altitude are colored
green. When altitude data is lost, objects are shown in
cyan. Obstructions are shown on the Custom Map and
in the Terrain function. For information on the Internal
GMX 200-Based Terrain color coding, see the Terrain
Function description in the Detailed operation section.
Review the Limitations section in the front of this guide.

and Menu Items (Page 4)
Current coverage for obstructions is North America
only and are drawn only when the zoom scale is 50
NM or less.
traffic
The Traffic option turns the display of traffic infor-
mation on or off. ADS-B Traffic information includes
the location and identifier of a reporting aircraft, its
direction of travel, elevation, and the estimated path
for the selected time interval. See the section on the
Traffic mode for more details on how traffic informa-
tion is used.
A small thumbnail presentation of traffic is pre-
sented in the upper left corner of the display. Traffic
targets can also be overlaid on the Custom Map page.
The Traffic function is an optional installation.
Check your Approved Flight Manual Supplement to
verify if this feature is available. Review the Limitations
section in the front of this guide.
Strikes
The Strikes menu option controls the display of
lightning strike information if the GMX 200 receives
strike data from an external source, such as the
WX500. Each reported lightning strike is shown as an
“x” on the display. Strikes are not shown if the zoom
scale is below 20 NM, or above 400 NM.
