Garmin AXIS vs G3X Touch vs G500 TXi: Which Garmin Panel Upgrade Fits Your Aircraft?

Where AXIS fits

Garmin describes AXIS as a new generation of highly integrated flight displays for certified Class I/II aircraft and experimental aircraft. That is the same broad category of piston singles and twins where G3X Touch and G500 TXi have been most popular, covering airplanes like the Cessna 172 and 182, the Piper PA-28 Cherokee and Archer, the Beechcraft Bonanza, and the Mooney M20 series. Garmin also says certified-aircraft approved model list and STC information can be viewed through Garmin Support Center, which means aircraft-specific eligibility still needs to be confirmed before any installation decision is made.

At the same time, Garmin is directly promoting AXIS as an easy upgrade from G3X Touch. Garmin says AXIS shares the same panel cutout and screw points as G3X Touch and can use many existing sensors and components, making that comparison especially important for owners already looking at the G3X path.

AXIS vs G3X Touch

The clearest difference is that Garmin is framing AXIS as the next-step option for owners who want more display area and more integration. Garmin says AXIS offers more display area than G3X Touch and is available in 11.6-inch, 8-inch portrait, and 8-inch landscape configurations.

Garmin also says the 11.6-inch AXIS display can include optional built-in IFR GPS/NAV/COMM and audio panel functionality. That could be a meaningful advantage for owners who want to simplify panel architecture rather than build around multiple separate avionics boxes.

AXIS vs G500 TXi

The G500 TXi has long been a familiar name in certified-aircraft glass panel modernization. Garmin previously described the G500 TXi as intended for Part 23 Class I/II aircraft under 6,000 pounds, which means it naturally shows up in many certified-aircraft upgrade conversations.

AXIS enters that same general buying conversation from a different angle. Garmin is emphasizing a more integrated display architecture, larger touchscreen formats, and optional built-in IFR GPS/NAV/COMM capability in the 11.6-inch display, but public launch information alone is not enough to claim that AXIS is a one-for-one replacement for G500 TXi in every aircraft or installation scenario.

Which owners should compare all three

This is the right comparison for aircraft owners who are actively planning a Garmin upgrade and want to understand where the newest system fits. It is especially relevant if you are deciding between a practical G3X Touch path, a more established certified-aircraft option like G500 TXi, or a new AXIS-based panel strategy.

The best choice depends on your aircraft, the certification path, the current avionics stack, your mission, and how much panel integration you want. AXIS may be the most exciting new option, but the smartest decision still comes from matching the equipment to the airplane and the owner's long-term plans.
