The GNC 300XL TSO delivers picture perfect GPS/comm technology and outstanding reliability. This panel mount combines GPS navigation with a 760-channel transceiver and high resolution DSTN display. The 300XL TSO shares the popular features of the GNC 250XL and is TSO-certified for non-precision approaches for the IFR environment.

View Graphics in Sharp Detail

Graphics appear in crisp detail on GNC 300XL TSO’s 80 x 240 pixel display — jagged lines disappear and smooth arcs and crisp alphanumeric characters prevail. For optimum viewing, a built-in photocell reads the light level and adjusts the display automatically from black-on-yellow to yellow-on-black for nighttime viewing.

Enhance Situational Awareness

Receive your choice of Americas or Atlantic or Pacific coverage from a huge Jeppesen® database. Like other Garmin panel-mount units, GNC 300XL TSO features front-loading data cartridges, so you can make data updates without removing the unit from the rack.

Save Space with Built-in Comm

GNC 300XL TSO also delivers clear communication from its 760-channel VHF transceiver. Comm features include auto squelch control, instant standby and emergency channel select and frequencies transfer from the database.
