Looks like the eXport is dead, and was pretty much dead by the time it was released as they only ever made an eXport to 30pin connector, a eXport to lightning connector cable was never made.

Wierd that they are still fitting these eXport sockets in new aircraft when virtually no-one is using it or can use it. I guess it's a case that the cable and connector is included on the wiring loom so they might as well fit it...
