At this year’s Aircraft Electronics Association show in March, Garmin International (Stand 1367) introduced the long-awaited successors to the 14-year-old Garmin GNS 430/530 navigator series, the new GTN 650/750 touchscreen panel-mount navigator/radios. Since then, the U.S. cockpit innovator has added another new series in its large-display avionics, the new G2000 with a touchscreen controller.
While the functionality improvements of the GTN series are compelling, what is significant is that they bring full touchscreen control on the display itself to Part 23 cockpits. And in a surprising move, Garmin obtained FAA TSO certification of the GTN series and approved model list certification for installation in most Part 23 aircraft before making the AEA announcement. The new GTN 650 and 750 are the first certified aviation touchscreens. Prices are $11,495 for the GTN 650 and $16,995 for the 750. An optional remote audio control system, the GMA 35, costs an additional $2,995.
