A Tiny Card That Changes Everything
If you’ve ever juggled paper charts, SD cards, and manual data entry before a flight, you’ll instantly understand the appeal of Garmin’s Flight Stream 510.
This small, SD-card-sized module might look simple — but once installed, it quietly transforms your cockpit. Suddenly, your iPad or Android device becomes an extension of your avionics. Flight plans, weather, traffic, and databases all sync wirelessly in seconds.
It’s part of Garmin’s Connext ecosystem, which connects tablets, phones, and even passenger devices with your avionics for a truly modern, connected cockpit.
🔍 What the Flight Stream 510 Actually Does
Installed directly into the SD card slot of a GTN 650/750 (or compatible G500/600 TXi and G1000 NXi), the Flight Stream 510 acts as your wireless bridge between panel and tablet.
Here’s what it brings to your flying life:
- Two-way flight-plan transfer: Instantly push or pull routes between your avionics and the Garmin Pilot App — no knobs, no fuss.
- Database Concierge: Update navigation, terrain, and chart data wirelessly through your tablet at home or at the airfield.
- ADS-B and weather display: Connect it to a GTX 345 transponder or GDL 88 receiver and see traffic and FIS-B weather right on your device.
- Backup attitude display: When linked to an AHRS-equipped system (like the G500 TXi), you’ll have pitch-and-bank backup right on your tablet.
- SiriusXM audio control: If you’ve got a GDL 69A, stream or control your satellite radio directly through the Garmin Pilot App.
🧩 Installation couldn’t be easier — it replaces your existing SD card and requires no extra wiring. In minutes, even older Garmin systems gain the connectivity of brand-new avionics.

✈️ A Flight in the Real World
Picture this: you’re sitting in your Cessna 182, running a GTN 750 and GDL 88.
Before you even leave home, you’ve built your route in the Garmin Pilot App on your iPad.
When you power up at the airfield, the Flight Stream 510 connects automatically.
Your route appears on the GTN screen — perfectly synced.
In flight, weather and ADS-B traffic paint live across both the panel and your tablet.
Then ATC calls: “Cessna N1234, cleared direct to ELN.”
You type it into your iPad, hit enter, and the GTN updates instantly — no button-twisting, no cockpit juggling.
It’s seamless, simple, and saves time exactly when you need it most.
