System Info - Garmin MX20 User Manual

Detailed Operation

System Info

The System Info page includes information about the
software and database versions of the MX20. The data
port status is also displayed. The Data port status
description allows you to verify correct system installation
and to monitor the health of each of the devices sending
information to the MX20. Use this information when you
contact your dealer or the factory.
GPS and Datalink Status
For GPS/UAT equipped installs, the SYS/INFO page
shows additional details for both the internal GPS engine
and the data-link status. When the MX20 is connected to
a legacy UAT, the ADS-B and TIS-B Data Link Status
lines are displayed. When the MX20 is connected to a
GDL 90 UAT, only the ADS-B Data Link Status line is
present because there is no differentiation between ADS-B
and TIS-B target data.
GPS satellite usage and signal strength are presented in
the upper right of the info page in addition to each
satellite's position in the sky. If no GPS is installed in the
MX20, the text "Internal GPS Not Available" will be
shown.
