I figured I would ask here first...what do you guys recommend. I have the factory navigation in my 2005 x5. I don't have the dsp or a sub, but I do have the cd changer. I have auxiliary input also, which I currently use to play my ipod. I would like to be able to get the videos off of my ipod touch or older ipod video and view them on the nav screen. What is the easiest way to do this?
