Note: Use the matrix as a general guideline only. GPS manufacturers are constantly changing their
products. Always refer to the Installation Manuals that come with the GPS/FMS to confirm
configuration and setup parameters. Additionally, keep in mind that not all GPS configurations
can be used with all aircraft.
There are two interface configurations that the MFD uses to connect with the GPS:
● GAMA 429 with Intersections
● RS-232
EX500/EX600 MFDs support both GAMA 429 and RS-232. However, GAMA 429 Graphics with
intersections is the only configuration from the GPS capable of providing heading information if the
GPS is being used as the heading source (see Section 5.11, “Map Heading Source Setup” on page 64
for a complete explanation on setting up the various heading configurations within the MFD).
5.5.1 GAMA 429 Graphics Setup
If your GPS is capable of output from GAMA 429 Graphics with intersections, use the wiring diagram in
Appendix G: GPS/FMS System Wiring, on page 96 when installing the MFD.
Note: Using a 429 graphics output allows for the display of curved flight segments and approach
data, if that data is available.
➤ To setup a GAMA 429-capable GPS:
1. From the Maintenance Mode Page, press GPS Setup. The GPS Setup Page displays:
2. Configure the following:
■ Receiver—Select GAMA 429 Graphics Format.
■ Port— Select ARINC1.
Note: Selecting Port=None indicates that a GPS is not connected to the MFD. In this case, the MFD
software does not expect GPS input.
