Documentation says it's still beta, experimental, etc. But it's said that for over a year.
Is anyone using it? And can it be used to plug into the Aux port in a manner similar to the kludgey setup of connecting a cable to the bottom of the Celestron handset? Or does it have some other purpose?

Second this. I can get my Stellarmate X to connect to my CGX using the PC port, but the pointing is a mess. Jasem - You were looking for logs from CGX mounts using the AUX driver (I think) a while back. Still need them?

Similarly, I don't see an option to turn on PEC playback in the AUX driver like on the GPS driver (although it doesn't work for me). That would be a nice addition.
