I had it working with a GDL 39 3D and later with a Garmin 345 R transponder. Worked great with both.
Nice. The Cardinal has both the GDL39 (for the 696) and a GTX330ES (for the 530W/430W pair). I added a Flightstream 210 a while back to talk to ForeFlight, so the 39 provides traffic and weather to iPads too.
Waiting for a call back from the shop, trying to figure out what minimum labor effort they’ll demand to sign off on the change. It seems to me it should be relatively painless since the serial connection to the 39 can be replaced with Bluetooth, but I’m sure they’ll tell me something I’ve overlooked.
