Hello Jason,

You will need to install a GAD 29. See page 7-17 of the Rev. 5 G5 Installation manual.

Note that your GNX 375 will also get pressure altitude from the G5 via the GAD 29, so you don't have to worry about any other connections for it to have everything it needs for ADS-B In/Out.

This diagram has some extra stuff, but we mainly want to point out that if you add the new GAD 13 with OAT probe and GMU 11 magnetometer, not only will the G5 display OAT, TAS, Winds, and Density Altitude, but the G5/GAD 29 will share this data with the GNX 375 allowing it to also display winds and other information.
