No audible yet to my knowledge. I was also interested, but no app or widget exists for the matter. The podcast functionality is completely rubbish, it is just the basic audio player start/top/prev/next and no memory function. Better use your mobile phone and save on battery with the watch.
This said, I'd love for Audible to produce some useful adaptation of their app for Garmin devices. Even for 3rd party developers to port their audiobook players would greatly enhance the experience. My explanation why that is unlikely is the battery drain it will cause. After all, this is a sports watch with tiny battery and no mobile phone in a smaller package.
