These upgrades will be available on all new model 480B in 2023.
That new panel is designed around a Garmin G500H TXi EFIS display. The G500 features a robust and easy-to-use digital flight display. Its touch screen interface makes it much quicker and more intuitive to use than the old button and knob system.
Accompanying the G500 is a Howell digital engine instrument system (EIS) incorporating all the engine monitoring functions as well as the Caution and Advisory System (CAS).
Rounding out the new cockpits are new avionics from Garmin including GTN 750 and 650 TXi capable to interface with each other to save panel space and to simplify operations.
