Garmin GDL 39 / 50 / 51 / 52 Power / Data Cable For G3X (Bare Wires)

Add to Wishlist
Part# 11-10735
MFR Model# 010-11686-40


This replacement cable has bare wires at the end so you can hard wire your Garmin G3X or portable directly to a GDL 39 / 50 / 51 / 52 and DC power source. This connection allows you to send NMEA data as well as the GDL 39s ADS-B info over the cable.


Honestly This is the worst Garmin product I have ever had to buy. I have had to replace about 7 of them over the last 3 years. I use them for my GDL 52 that I move between 3 aircraft. The plug breaks and falls apart. I own $100,000 in Garmin equipment G1000H, autopilot, radios, Transponders, traffic systems, all of the portables since the 195! Garmin knows they are junk but we are stuck. Thank you for stocking them Aircraft Spruce. I buy two at a time Not your Fault

What can you say about a cable? I used it to wire a serial connection into my Garmin G3X and provide power to the GDL 39. Worked perfectly, nice quality.

Great addition to the airplane.

Works as expected for providing ships power to the GDL-39 BUT you will also need Garmin Part Number 010-11206-15 to supply ships power to your GPSMAP 695/696. I bought this cable thinking it would supply power to both units and was disappointed to find that I would need yet another expensive cable to supply power to both units. Functional, but overpriced.
