I would agree with Joseph and Markus that prep cast would be excellent for your use case. The information is relayed in a very digestible manner, and the test preparation in my opinion was by far the best on the market.
I also pursued audio and visual learning methods as they better helped me learn, so I can totally relate to your experience.
The Prepcast offered here will work perfectly for what you're looking for. I listened to Cornelius during my daily commute everyday, utilized the practice quizzes and exams, and passed on the first try.
Well, then the PMPrepCast is the ideal solution for you. You can download all the Lessons and listen to them while you're commuting.
Corenlius explains all the content in such a way that you don't even need to watch the video while listening to him.
There is no better option out there from my perspective.
