Garmin has received FAA approval for several supplemental-type certificates that allow for upgrading the Cessna Citation CJ2 to a full Garmin avionics package. The Garmin avionics replace the CJ2’s original Collins Pro Line 21 suite; Garmin is also developing a similar upgrade for the CJ1.
The CJ2 upgrade features two G600 TXi touchscreen flight displays, TXi engine indication systems, GTN Xi navigators, and a GFC 600 digital autopilot.
Several options are available with the CJ2 upgrade, including the GWX 8000 StormOptix weather radar with auto mode that automatically adjusts tilt and gain settings to accurately profile weather cells so pilots can analyze returns from hazardous storm cell activity.
The optional PlaneSync GDL 60 connected aircraft management system uses a 4G LTE cellular connection or Wi-Fi for automatic avionics database updates and can run on its own battery so that pilots don't need to be present to oversee manual updates. PlaneSync also enables pilots to check fuel quantity, database status, GPS location, temperatures, and other information remotely using the Garmin Pilot app.
In 2025, Garmin will add automatic post-landing transmission of flight and engine log data.
Also optional is the GMA 35C Bluetooth audio panel, GTX 345R remote transponder with ADS-B Out and In capability, GDL 69A SiriusXM datalink, GTS traffic systems, and GSR 56 Iridium satcom for worldwide weather, voice calls, and messaging.
