2.1.1.23 Bluetooth
The GDU 4XX displays in a G3X Touch system include Bluetooth transceivers. This allows a wireless connection to a tablet computer, using Garmin Pilot™ or another application that supports the Garmin Connext protocol. The tablet computer can receive GPS position and attitude data from the G3X Touch system, and can exchange flight plan information with the GDU 4XX or with a connected GTN navigator. In an installation with multiple GDU 4XX displays, the Bluetooth connection to the tablet computer should be made to the PFD1 GDU only.
