Gulf Coast Avionics Upgrades CJ1 with Garmin ADS-B
This was the company's first GTN touchscreen installation with a CJ1.
Gulf Coast Avionics upgraded this CJ1's panel with dual touchscreen Garmin GTN 750s, ADS-B OUT and IN, WAAS LPV, and a Flight Stream 210 wireless gateway.

Gulf Coast Avionics of Lakeland, Florida, has completed a Garmin ADS-B OUT and IN upgrade that includes touchscreen navigators, WAAS LPV approach capability and iPad cockpit connectivity in a Citation CJ1. The STC was developed by JetTech.


The upgrade includes dual Garmin GTN 750 touchscreen GPS/com navigators, dual GTX 345 Mode S extended squitter transponders with dual-link ADS-B OUT and IN capability and a Flight Stream 210 gateway that enables wireless connectivity between the GTN 750s and mobile devices. The WAAS LPV approach capability will enable the CJ1 to be flown to many airports that previously weren’t served by precision instrument approaches.


“This was our shop’s first ADS-B-compliant Garmin GTN touchscreen installation in a CJ1, and with our prior experience with Citations it turned out to be a pretty straightforward project,” said Gulf Coast Avionics sales representative Matt Schloss. “We did have to create a new wiring harness to interface the new avionics with the legacy Honeywell EFIS and autopilot. Everything else was done following the JetTech STC.”


“The customer was absolutely thrilled when he saw the new panel for the first time,” said Rick Garcia, president and CEO of Gulf Coast Avionics. “He now has a reliable airplane that will meet his business and personal travel needs well into the future.”
