So I presume still no joy with Garmin?
I have a GTN650 and GTX-345. Bluetooth only but I had hoped there might be a USB Bluetooth device that would allow me to connect.
With all that power in the cockpit and Garmin Pilot available on my tablet, I still prefer the iFly740. I can see it any light and it never over temps. But I ditched my homemade Stratux (actually re-purposed the Rasberry Pi) and now I miss my traffic and WX.
Any options?
