SELECTION BETWEEN MULTIPLE NAVIGATORS
NOTE: On a standalone MFD, touch 'GPS' in the lower left corner of the
display to switch between 'Internal' and 'External' navigation sources.
The G3X Touch CDI Source button in the PFD Options Window becomes available
when more than one source of navigation data is configured. The CDI Source button
toggles between the available navigation sources (e.g., between the internal G3X Touch
GPS and external SL30 VLOC sources, between an SL30 and a GNS 430, or between
two GNS 430s, etc.). Refer to the Flight Instruments section for more information.
USING MAPMX SERIAL DATA INPUT FORMAT
When using a WAAS enabled external GPS navigator (i.e., GNS 430W/530W, GNS
480 or any GTN Series navigator), and configuring an RS-232 input for ‘MapMX’ instead
of ‘Aviation In’, a more accurate depiction of the flight plan legs are displayed on the
moving map (i.e., holds, procedure turns, etc.). Non-WAAS external navigators do not
support MapMX. Refer to the G3X Touch Installation Manual for more information.
EXTERNAL GPS NAVIGATOR FAILURE
In the event that all configured external GPS navigators fail, the G3X Touch reverts
to its internal VFR GPS for navigation and flight plan modifications.
ADS-B DEVICES (OPTIONAL)
The G3X Touch is also compatible with the following ADS-B devices:
• GDL 50R
• GDL 52R
• GTX 345(R)
• GNX 375
