Common questions
Can I install Garmin GTN 650/750 in my King Air?
Yes — STCs exist for most King Air variants. Verify your specific model and serial range with the GTN's STC list before purchase. Listings link to relevant STCs where applicable.
What's the difference between exchange and outright purchase?
Exchange means you ship your core unit in to swap for a serviceable one (typically at a lower price). Outright purchase keeps your old unit. Listings clearly mark which sale type is offered.
Are ADS-B Out compliance packages still available?
Yes, though demand has cooled since the January 2020 mandate. Most listings now are exchange units or take-out parts from upgrades.
