Compatible Equipment

GRT Systems are Specifically Designed to Play Nice with Other Manufacturers’ Equipment

Every builder has his or her own taste when it comes to devices such as weather & traffic information, radios, transponders, and GPS units. We strive to give builders a choice when it comes to third-party equipment. This page is an overview of popular choices of our customers, with equipment supplements for some to help you install and use your product to its full potential with a GRT EFIS system. Check this page often for updates, as we are always adding to our equipment supplement library and third-party vendor list.

Equipment Supplements

These “mini-manuals” explain how to install and set up popular devices and avionics that work with GRT EFIS systems. You can pick the ones you need, print them out, write notes all over them and store them with your aircraft’s electrical system diagrams. Check back often for new releases or email us for special requests. We often create new supplements based on customer requests and then post them here for everyone’s benefit.

Note: Only Horizon 10.1 and HXr EFIS systems are capable of full remote control of com radios, nav radios, and intercoms.
