• GMU 44 – The Magnetometer measures local magnetic field and sends data to the AHRS for processing to
determine aircraft magnetic heading. This unit receives power directly from the AHRS and communicates with
it via an RS-485 digital interface.
• GDL 69A – The Data Link Satellite Radio Receiver provides real-time weather information to the G1000 MFD
and PFD Inset Map, as well as digital audio entertainment. The Data Link Receiver communicates with the
MFD via a HSDB connection. A subscription to XM Satellite Radio Service is required to enable the GDL 69A
capability.
