Garmin 660 MP3 player and play lists

 

I listen to podcasts on my 660. The process I use is to first copy the podcasts from itunes on to the SD card. Then I use Winamp to create an m3u playlist file. This works well but it takes a long time. Does anyone have a suggestion for how to get podcasts off itunes into playlists in one step? Itunes playlists do not work with Garmin.

Thanks
