Garmin AXIS: the radio stack just moved inside the display

Garmin's brand-new AXIS flight displays build a TSO'd IFR GPS, NAV/COMM radio and audio panel right into the screen — four boxes collapsed into one. If you're planning a from-scratch panel, this rewrites the layout. Here's what it means, what it costs, and why we think it's a game changer.

Word Gets Around

What Pilots Say

★★★★★

"Treasure Coast Avionics is one of the best avionics shops I have ever seen. Lennon and Cathy are terrific. Not only did they come in under budget — which was amazing — but they helped me set up and use the new G3X with EIS Lennon installed. I flew my plane down from the Northeast just so they could work on it. They came highly recommended, and they did not disappoint."

Flying for More Than Fun

Aviation is at its best when it serves people. Treasure Coast Avionics proudly supports volunteer pilot organizations that fly disaster relief and community support missions — with our hands, our bench, and our parts bin.

Volunteer Pilot Group

A Florida-based 501(c)(3) whose member pilots fly charitable missions across North America — education, healthcare, and disaster relief — at no cost to those served. We help VPG keep its volunteer fleet mission-ready by supporting safety equipment upgrades in their aircraft.

Reboot Charity

rebootcharity.org

A 501(c)(3) that provides technology, tools, and logistics so self-funded volunteers can do more — including evacuation, supply, and volunteer transport flights into disaster areas. After Hurricane Melissa, Reboot and VPG together supported more than 220 relief flights into Jamaica.
