GTN 750 cross feed

[the400kid]

I recently had work done on my panel and noticed that the cross feed between the GTN 750 and the portable AERA 510 is no longer working. The GTN version was upgraded which tells me that something happened to the configuration. What I am seeking here is how to configure the crossfill from the GTN system through the system setup. I have made changes to the configuration in the past and am no stranger, but I'm just not sure where in all of the options the crossfill is setup.

I would take the plane back to the shop but they are out of the area and I'd like to fix it myself if possible.

How are they connected? Flight Stream? Serial wires?

Just looking at the wiring diagram in the 660 Pilot's Guide, maybe both sides have to use MapMX Format 1.

While the aera 660 supports MapMX, I think the 510 does not. I seem to recall the 660 being the first portable to support MapMX.

The GTN version was upgraded

Did you get new hardware, or software / firmware upgrade?
