Thanks both Mobileum and shawnsheridan
I have spent hours researching this but there seems to be conflicting information. BMW in some of their documentation say you must have a snap-in to play video and in some documentation says that to use the apps you must have a snap-in. No where apart from this thread have I read anywhere about using the Aux input for Video. The lead that shawnsheridan suggests is interesting in that its description is "BMW In-Car iPod/iPhone Audio Video USB Adapter Cable 61122179623" which mentions video, although the description only mentions Audio. Does the video get transferred as video or is it streamed digitally over the USB? Does anyone have both Media/Video and Apps working with an iPod Touch using a cable only and no Snap-in ?
