Yes this is a good and most important point....sorry for the omission....
It is up to the maker of the ES enabled transponder to support a given GPS.
To add further detail to this subject:
"3.3.B(2)
Unless the ADS-B equipment manufacturer has analyzed the interface between the
position source and the ADS-B equipment you are installing, and specifically listed the position
source in the ADS-B equipment’s installation manual, you must provide an analysis of the
interface between the position source and the ADS-B equipment which demonstrates that the
position, velocity, position accuracy, position integrity, and velocity accuracy information taken
from the position source is properly interpreted by the ADS-B equipment.
Note: This analysis will require engineering design data
from the ADS-B equipment manufacturer and the position
source manufacturer."
This pretty much requires that the ES enabled transponder manufacturers must formally support the position source used. Just because it may work if connected won't cut it unless that position source is specifically listed in the installation manuals of the ES enabled xponder....I doubt the manufacturers are going to give up their engineering design data for both the GPS and the ES enabled xponder.....
