Garmin is offering rebates up to $3,500 on its G3X single or dual screen system for Experimental and light sport aircraft until Dec. 10, the company announced. The G3X is a primary flight display, multi-function display, and engine monitor that is virtually identical to the G300, the centerpiece of the instrument panel in the Cessna 162 Skycatcher. (Watch the avionics' performance through loops and rolls in this AOPA Live video.) Garmin also said it will make a major expansion to its display area at EAA's AirVenture in Oshkosh, Wis., and add a G3X area to it. The G3X borrows much of its technology from Garmin's popular G1000 avionics suites and offers similar high-end features such GPS-derived synthetic vision, an integrated autopilot interface, terrain, obstacle, and traffic warnings, and satellite weather.
