A 1/2 inch ID grommet fits nicely onto the knob.

I used this one for a 5th gen nano with a 930BT. Worked fine and it displayed album art. Didn't try a video. Pioneer CD-IU50V iPod / iPhone Interface Cable for Select Pioneer Multimedia. Around $15 with Amazon Prime. http://www.amazon.com/gp/product/B004SQRWWQ/ref=oh_details_o01_s00_i01

My 9310BT did the same thing with an audio book and I thought that I had hit pause before switching sources. It was a pain trying to find where I left off in the story.
