Wireless Bluetooth transceiver that can communicate with tablet computers and other Garmin
devices that support Connext interface protocol. Refer to G3X Touch Pilot's Guide for Certified
Aircraft (190-02472-00) for guidance in using Connext Bluetooth connections.

CAN and RS-232 interfaces to communicate with Garmin LRUs and other devices. Refer to the
appropriate sections in the G3X Touch EFIS Part 23 AML STC Installation Manual (190-02472-

One GDU 470 may be installed as a single PFD configuration (see Figure 2-2) or two GDU 470s as a
dual PFD and MFD configuration. EIS is only supported on a GDU 470 configured as an MFD in a dual
display system. A GDU 470 may also be installed with a GDU 460 in a dual display configuration.
The display on a 7" GDU when configured as an MFD (in a dual display configuration) does not have split
format functionality in normal mode but is available in reversionary mode if the PFD fails.
NOTE
EIS is not supported in a single GDU 470 installation.
