There's a cab for it but for some reason I can't upload files here. Let me try and put it somewhere else. It worked on the mogul, haven't tested it on my pro yet.
EDIT: Also, anyone got a working bluetooth audio cab yet? I listen to audiobooks on my BT all the time, but my old cab for this isn't working anymore.
EDIT2: Ok, tested and it worked. Here you go:
