Garmin GTN Updates

Garmins latest software for the GTN navigators (V6.5) offers compelling new features. GTNs come in both the GTN 700 and GTN 600 series. The patriarch is the x50 (650 or 750) with GPS/NAV/COM capabilities; whereas the x25 has only GPS. The 600 and 700 differ in the screen size and the 700s ability to control an embedded audio panel. With the larger screen, the 700 can also display georeferenced (Jeppesen or AIS) approach charts.

GTN software V6.5 introduces enhanced Vertical Navigation (VNAV) capabilities, displaying and allowing modification of altitude restrictions for approaches, STARs, and SIDs.
The update adds automatic cold temperature compensation, which calculates corrected altitudes for operations at cold temperature-restricted airports.
New features improve usability, including QWERTY and "half ABC" keyboard layouts, and an "Along Track Offset" function for defining waypoints with specific altitude restrictions.

Full disclosure: I’ve had a 750 and 650 in my Mooney Ovation since Garmin first released the GTNs in 2011. Since then, I’ve gone through eight software updates, each one adding additional features and capabilities.
