Garmin’s New GNC255: Intelligent Navcomm

Over the years, the role of the standalone navcomm radio has changed from a primary system to backup, often playing second fiddle to all-in-one integrated mapcomm systems. But we’ve wondered if the traditional navcomm radio might make a comeback if it had more advanced features—perhaps a built-in database for searching frequencies and better yet, an interface that can connect with a panel-mounted GPS for sharing data. Garmin has done just that—replacing their current line of SL-series navcomms with a completely redesigned line, to include the GNC255 navcomm and comm-only GTR225. These radios are engineered using technology which comes from high-end panel-mounted avionics in the Garmin line. The new navcomms have plenty of smart features, can interface with portable and panel GPS units, and are compatible with a healthy variety of nav displays. We think the GNC/GTR products are the evolutionary radios the industry has been waiting for.
