Garmin G5 and Piper AutoControl III - works?

[frontrangeflyer01]

I'm installing dual Garmin G5's with a GAD 29B adaptor into my Cherokee Six, which has a Piper AutoControl III autopilot (not the IIIB).

My shop is also installing the Century 1C388-3 Radio Coupler for use with HSI's that have heading and course datum outputs.

Has anyone successfully got the Garmin G5 GPSS roll steering to work with their AutoControl III?

I understand that it SHOULD work (on paper), since the AutoControl III is very similar to the Century II, which Garmin specifically supports. Just checking to see if it's working in the wild

Thanks in advance for your help!
