# PMS GTN750 The Garmin GTN750 is a highly advanced touchscreen avionics unit. It combines GPS, NAV, and COMM functions into a single, intuitive device. With its high-resolution display, the GTN750 offers pilots a user-friendly interface for flight planning, navigation, and communication. The system supports a wide range of features, including graphical flight planning, traffic and weather information, and terrain awareness. Its seamless integration with other avionics and straightforward upgrade paths make the GTN750 an essential tool for enhancing flight safety and efficiency. Some operators have retrofitted their 727s with the GTN750. Sometimes it's linked to the autopilot, and sometimes it's only used as a standalone module. We have integrated it with the entire aircraft for maximum convenience, allowing control of not only the autopilot but also the COM/NAV frequencies and the transponder through it. The PMS GTN750 is available in a free and a paid version with a different feature set. Please refer to the [PMS documentation](https://pms50.com/fs2020/gtn750/documentation.pdf) for installation and use. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
